All about the new Microsoft Surface tablets, Windows and Windows 8 Pro RT

3:51:00 PM

Microsoft can join the manufacturers of tablets with 2 gadgets that will hit the market in November to three months after Windows 8. IT giant is trying to get stronger in the relevant segments of the market , with a tablet running Windows 8 UI only with Metro, Microsoft Surface RT, and a tablet running Windows 8 Pro, Surface Pro, which allows the use of desktop applications.

An important detail is that the two tablets Surface will be launched with two special cases: Touch Cover with a thickness of 3mm, a case with the role of Cover Type tasatura and stand and a thickness of 5mm, which includes a trackpad .

Microsoft Surface vs. iPad

Comparison between Microsoft Surface and other tablets can be difficult since the company chose not to submit complete specifications, write TheVerge . Microsoft seems to adopt the Apple model to focus on end user experience without too many figures portray.

Retina Display screen without having the iPad tablet Microsoft Surface could become a strong competitor to Apple tablet, especially in version Surface Pro .

You can choose between a tablet with a simple operating system and restrictive and a tablet PC that offers a practical experience, consumers could abandon the iPad.

Microsoft Surface vs. Android and Windows 8

Asus Transformer Pad is probably the most similar product already launched Android, but Microsoft could be just the advantage of operating system more complex.

Microsoft Tablet battling and competition from other Windows 8 tablets Asus Tablet 600, Acer Iconia W510 and prototypes created by Toshiba, HP, Dell and Lenovo. One thing is now clear: Windows 8 tablets manufacturers are not too happy with Microsoft competition.

The most important detail that Microsoft Surface is omitted from the presentation is price. For many buyers, specifications and functionality can be properly judged only in relation to price .

The only detail that Microsoft unveiled on pricing is that it will be "competitive" with the suggestion that as a Surface ultrabook Pro will cost.

Do you think Microsoft could dethrone tablets new rule iPad?

SafeGuard Disk Encryption for Mac 5.5

8:37:00 PM

Sophos SafeGuard Disk Encryption for Mac offers full-disk encryption (FDE) for the Mac, with protection at boot time from unauthorized access. FDE scrambles the entire contents of a disk drive, rendering it ostensibly unrecoverable without access to the long encryption key used, or a shorter account passphrase that unlocks that key.

FDE makes your data secure when someone gains unauthorized physical access to it while your computer is shut down. If a computer with an FDE-protected drive is booted and running, the data is still susceptible to various forms of extraction using forensic tools, even if there's a password lock enabled in OS X. But when the computer is shut down, it's as close to Fort Knox as one could hope.

With Lion, you have the option to use the built-in FileVault 2 FDE that replaces the directory-only encryption provided in the original FileVault system introduced in OS X 10.3 Panther. FileVault 2 works quite well, is integrated into system accounts and system boot time, and relies on AppleCare support as an optional backstop to help with extreme cases in which an account password fails or is forgotten and a separate emergency recovery key has been lost.

SafeGuard, compatible with Lion in version 5.5, has to scale a mountain to convince users to purchase a feature that's otherwise built into the OS. A third-party encryption tool has to do the job right, but also have features or options that set it apart from FileVault 2. (SafeGuard provides a separate installer for Mac OS X 10.5 and 10.6. If you upgrade from Snow Leopard to Lion, it is vitally important to follow Sophos's instructions. An upcoming SafeGuard 6.0 release will work on 10.5 through 10.7, however, according to Sophos.)

Sophos requires that you create unique accounts, separate from Mac OS X, including at least one administrative account.

SafeGuard doesn't quite get there. There are enough rough edges and confusing bits that don't place it anywhere near the ease with which Apple enables FileVault 2, which make SafeGuard hard to recommend highly. Sophos could sand down the interface and documentation friction, while adding a couple of compelling features. However, SafeGuard is a good choice for anyone who prefers not to rely on Apple for their encryption needs for whatever reason.

Using SafeGuard

Sophos relies on its own user accounts set up as User and Admin categories, which means extra account management instead of using Mac OS X authentication. This is clearly required because at startup time SafeGuard has to rely only on what its own system can manage—it can't access Mac OS X or accounts. We can’t ding the product for that, but it's more complicated than Apple's integrated ability.

You set up at least one Admin account to start encrypting the drive with a single click. There's an option to use Fast Mode, which has no explanation in the program or documentation as to what "fast" means. I had to query the company, which explained that with Fast Mode disabled, disk encryption takes a back seat to whatever the user is doing. In Fast Mode, encryption consumes all available computational power, which might slow down other activities.

Admin accounts can enable and disable encryption on partitions, and create and delete regular users. A User can log in at startup. User accounts can be backed up with a third form of account, Recovery, which are one-time use logins assigned to specific User accounts, and which are meant to help in case you forget or lose the password for a User account.

Sophos could provide a more sensible handholding walkthrough here. It should have the option of an assistant that guides you through creating an Admin user, and gives you the opportunity to create a regular User and one or more Recovery accounts. Instead, I had to stumble through the documentation to figure out the precise relationship.

Any FDE system needs to offer tools to help you when things go awry, as normal disk utilities won't work. Sophos includes options in its program's Users tab in a gear pop-up menu, but they're rather hard to parse there and in longer explanations in the documentation. I sorted it out, but I don't expect that even an advanced user will find the explanation straightforward.

Sophos has three recovery options, but it's really two ways to make bootable media, with a third menu item to export your encryption and authentication data. You can either create a generic bootable image without your login bits (which lets you separately attach your authentication data), or you can create one that's bootable and has the necessary credentials for the specific computer from which the disk was exported.

What Sophos doesn't explain is that you need to take the disk image and create a bootable volume from it. This is trivial in Disk Utility. Drag the disk image into Disk Utility, where it shows up in the bottom of the list at left. Insert some kind of media, such as a USB thumb drive, that you're willing to erase one or more partitions of. Select the disk image icon, and then drag the partition of the drive you're using into the Destination field. Click Restore. This creates an EFI-formatted bootable drive you can select at startup time by holding down the Option key. Would that these instructions (with some screen captures and more detail) were in the manual.

Sophos has its own EFI-based boot process that lets you enter a user or administrator account to start up Mac OS X. Only the keyboard works; mice and trackpads are unavailable.

I tested booting from a recovery image and performing various recovery operations, and they worked just fine. As with the rest of SafeGuard, the actual function is there masked by an unpolished interface. You can decrypt a drive quite simply, too. While logged in as an administrator, click Decrypt.

Limitations

SafeGuard also warns you in the documentation against backing up certain files in Time Machine, but doesn't provide a tool to exclude those automatically. SafeGuard can't encrypt external drives. And it requires the use of the keyboard in its boot manager, which makes it feel a bit more like using a newer PC BIOS than a Mac. Ostensibly, they didn't want to include mouse and trackpad drivers.

SafeGuard makes it simple to encrypt or decrypt an entire drive.

The only compelling reason to choose SafeGuard over FileVault 2 relates to boot-drive partitions. FileVault 2 only works on a Mac OS X's boot volume in which the Lion Recovery partition is installed and working. You cannot use a custom partition scheme, and users have reported all sorts of problems if they've messed with Lion partitions. SafeGuard doesn't have this problem. You can encrypt any number of partitions on the boot drive, and a Lion Recovery partition isn't a requirement.

Ivy Macs rumored to Launch April 8

7:42:00 PM

Earlier this month, leaked information suggested that Intel's next-generation mobile Ivy Bridge processors would debut in May, with a few models perhaps becoming available in April. The mobile Ivy Bridge processors are expected to be used in Apple's MacBook Pro, MacBook Air, and Mac mini lines.

A new report from Digitimes indicates, however, that the first Ivy Bridge processors may launch as early as April 8th, with both the mobile processors and desktop processors such as those used in the iMac debuting around the same timeframe.

Desktop CPUs to be unveiled include quad-core Core i7-3770K, 3770, 3770S, 3770T, and Core i5-3570, 3550 and 3450, with prices ranging from US$184-332. Additionally, the Core i5-3470T will be available in May priced at US$184.

Notebook CPUs Core i7-3920Qm, 3820QM and 3720QM will be released in April priced at US$1,096, US$568 and US$378, respectively. Other models including Core i5-3520M, 3360M, 3320M and ultrabook CPUs Core i7-3667U and Core i5-3427U will be unveiled later.

While the report also appears to confuse chipsets being released at the same time with the processors themselves, information on specific processor models does help offer some picture of what Apple might be able to accomplish in terms of updated machines.

The 3820QM and 3720QM processors in particular appear to be the natural successors to Apple's current processor options in the high-end 15" and 17" MacBook Pro models. Apple's upgrade route in many other cases is less clear given the company's propensity to use custom-produced chips and a limited first wave of Ivy Bridge processors. The Core i7-3667U and Core i5-3427U processors appear to be the only processors in the initial wave of Ivy Bridge processors to meet the thermal design requirements for the MacBook Air, with those processors apparently set for the later May debut.

Apple has been rumored to be launching a new 15" MacBook Pro with "Retina" display technology in the second quarter of 2012, matching the Ivy Bridge launch timeline. A new 15" MacBook Air has also been rumored alongside an update for the rest of the line in the first quarter of 2012. But with the appropriate Ivy Bridge processors apparently not debuting until May, it is unclear how Apple would meet this timeline.

Buying guide: Macs (2011)

7:22:00 PM

Planning to buy a new Mac for someone on your holiday shopping list? Such a thoughtful and generous gift is going to make someone very, very happy.

Now comes the hard part: Which Mac should you buy? That's where we come in. We've tested every standard-configuration Mac model currently in Apple's lineup, and we know each model inside and out. We're happy to help you make a decision.

This buying guide explains all the Mac models available and how they've changed from their predecessors. To read the full review for each Mac, click on the “Read our complete review” links. You can also get more details on how each Mac did in our benchmark tests. And we’ve provided links to help you find the best prices.

MacBook Air

The MacBook Air has become Apple's marquee laptop. Its thin, lightweight design makes it an ideal portable computer, and you no longer have to accept the features compromises that older MacBook Air models required.

The 2011 MacBook Air line uses Intel dual-core Core i5 processors, a vast improvement over the Core 2 Duo processors used in previous models we found the 2011 MacBook Air models are at least 1.5 times as fast as last year's 11-inch MacBook Air with a 1.4GHz Core 2 Duo processor. With some older games, however, the current models may suffer a hit in graphics performance.

The 2011 models' key new feature is the Thunderbolt port. Past MacBook Air models had only USB 2.0 connectivity; Thunderbolt gives the 2011 MacBook Air a high-speed connector, and widens the range of peripherals you can use. You can either get the proper adapters to connect FireWire, eSATA, USB 3.0, or other devices to the Thunderbolt port, or you can get Apple's Thunderbolt Display, which serves as a connectivity dock for the laptop.

When Apple discontinued the MacBook in July, the company thrust the MacBook Air into a new role. Apple's lowest-priced laptop is now the 11-inch 1.6GHz Core i5 MacBook Air () with 64GB of flash storage. (You may be able to find a refurbished MacBook at the online Apple Store, if you really want one.)

Configurations: There are four MacBook Airs: two 11-inch models and two 13-inch models. All come with flash storage and Intel HD Graphics 3000.

The entry-level 11-inch MacBook Air has a 1.6GHz Core i5 processor, 2GB of RAM, and 64GB of flash storage for $999.The other 11-inch MacBook Air has the same processor, 4GB of RAM, and 128GB of flash storage for $1199.Both 11-inch models feature a high-resolution LED backlit glossy display with a 1366-by-768-native resolution.

The only difference between the two 13-inch MacBook Air models is the amount of flash storage. Both 13-inch models feature a 1.7GHz Core i5 processor, but the $1299 13-inch MacBook Air has 128GB of flash storage, while the $1599 13-inch MacBook Air has 256GB.

Performance: The MacBook Air is quite capable of handling everyday tasks, such as emailing, Web browsing, using office applications, and more. You can even use it for editing short videos, and working with JPEGs from your iPhone or point-and-shoot camera.

The 11-inch MacBook Air is the slowest Mac in Apple’s lineup, but it's no slouch. It’s much faster than last year’s 13-inch MacBook Air. Also, the 11-inch MacBook Air, thanks to its flash storage, is about as fast overall as the $1199 13-inch MacBook Pro with a dual-core 2.4GHz Core i5 processor and a 5400-rpm 500GB hard drive. The 2011 13-inch MacBook Air is about 28 percent faster overall than the last year's 13-inch MacBook Air.

buying advice: Previous MacBook Air generations were thought of as niche laptops. But now, the 2011 MacBook Air is the ideal laptop for most Mac users. It's a great combination of performance and portability.

MacBook Pro

The MacBook Pro was actually updated twice in 2011. The first update was in February, and the most recent MacBook Pro line was released in October. The MacBook Pro continues to sport the aluminum unibody design that was introduced in 2008, but it has more features and processing power than the MacBook Air. Consider the MacBook Pro a possible replacement for an older desktop Mac.

The current models feature Core i5 and Core i7 processors that are slightly faster than the models released in February. The speed differences are bigger if you compare the current MacBook Pro line to the models released in 2010; most notably, the 2010 13-inch MacBook Pros used slower Core 2 Duo processors. The new 13-inch MacBook Pros still use only an integrated graphics processor, the Intel HD Graphics 3000. The 15- and 17-inch MacBook Pros have both the integrated Intel HD Graphics 3000 and a discrete graphics chip.

Configurations: There are five standard configurations of the MacBook Pro.

The entry-level 13-inch MacBook Pro, with a dual-core 2.4GHz Core i5 processor, 4GB of RAM, and a 500GB hard drive, costs $1199. The 13-inch MacBook Pro with a dual-core 2.8GHz Core i7 processor, 4GB of RAM, and a 750GB hard drive costs $1499.

There are two 15-inch models. For $1799, you get a quad-core 2.2GHz Core i7 processor, a 500GB hard drive, and a 512MB AMD Radeon HD 6750M discrete graphics chip along with the integrated Intel graphics.The next model up (at $1999) has a quad-core 2.4GHz Core i7 processor, a 750GB hard drive, and a 1GB AMD Radeon HD 6770M discrete graphics chip along with the integrated Intel graphics.

The 17-inch MacBook Pro is the same as the $1999 15-inch model but with a larger screen. It has a quad-core 2.4GHz Core i7 processor, a 750GB hard drive, a 1GB AMD Radeon HD 6770M discrete graphics chip, and the integrated Intel graphics. It costs $2499.

The 15- and 17-inch MacBook Pros are the only laptops in Apple’s lineup that offer a high-resolution antiglare screen option. It costs an extra $150 for the 15-inch MacBook Pro, and an extra $50 for the 17-inch MacBook Pro.

Performance: The $1999 15-inch MacBook Pro 2.4GHz Core i7 was the fastest laptop in ourSpeedmark 7 testing. The $1199, 13-inch 2.4GHz Core i5 MacBook Pro offers performance that’s similar to that of the $999 11-inch MacBook Air with a 1.6GHz Core i5 processor and 64GB of flash storage, but the MacBook Pro has features the MacBook Air lacks, including FireWire 800 and a bigger screen.

buying advice: The MacBook Pro combines the performance of a desktop computer with the portability of a laptop. If you want the fastest MacBook Pro, the 15-inch 2.4GHz Core i7 MacBook Pro is the one to get. If you primarily want a device for travel and are trying to decide between a MacBook Air and a 13-inch MacBook Pro, go for the MacBook Air, unless you really need the processing power for heavy-duty tasks or you want a computer with FireWire built in.

Mac mini

Designwise, the 2011 Mac mini hasn't changed much compared with its predecessor. It's still a small aluminum square that sits modestly on your desk.

The change that does stand out—and may influence your buying decision—is that the Mac mini no longer has a SuperDrive. If you want to burn music CDs or DVDs, or read data from an optical disc, you need to get an external optical burner, which costs $60 to $100. If you absolutely want an internal SuperDrive in your Mac, opt for a laptop or an iMac.

The 2011 Mac mini has a Thunderbolt port, which replaces the Mini DisplayPort in the older model. The Mac mini also has an HDMI port, a FireWire 800 port, four USB 2.0 ports, a gigabit ethernet port, an SDXC Card slot, and analog/optical-digital audio input and output minijacks. Wi-Fi and Bluetooth are built-in.

Configurations: The $599 Mac mini has a dual-core 2.3GHz Core i5 processor, 2GB of RAM, a 500GB hard drive, and Intel HD Graphics 3000 integrated graphics. The $799 Mac mini has a dual-core 2.5GHz Core i5 processor, 4GB of RAM, a 500GB hard drive, and AMD Radeon HD 6630M discrete graphics. You supply your own keyboard, mouse, and display.

Performance: In 2010, Apple released only one nonserver Mac mini model, which had a 2.4GHz Core 2 Duo processor, 2GB of RAM, a 320GB hard drive, and Nvidia GeForce 320M integrated graphics. The 2011 Mac minis are significantly faster than the older model: The $599 Mac mini is 32 percent faster, and the $799 Mac mini is 61 percent faster.

The Mac minis still lag signifcantly behind the iMacs, but for general-purpose use and editing of moderate-size videos, the Mac mini will do fine.

buying advice: The Mac mini continues to be a nice, affordable computer for new Mac users and shoppers on a budget. It has enough power for everyone except professionals who demand top performance. Be sure to shop around for an external disc burner if you really need an optical drive.

iMac

Apple hasn't changed the design of its aluminum all-in-one desktop computer for a few years now, because it's a design that works. It elegantly fits the components and display into an iconic form.

The company updated the line in May with new processors and graphics chips. The iMacs are available with 21.5- and 27-inch widescreen 16:9 displays.

The iMac comes with Apple’s Wireless Keyboard and Magic Mouse, but if you order online from the Apple Store, you can switch the keyboard to a wired version with a numeric keypad, and switch the mouse to an Apple Mouse or a Magic Trackpad, for no extra fee. You can opt for both a Magic Mouse and a Magic Trackpad for $69.

All iMacs come standard with 4GB of RAM, a SuperDrive, Wi-Fi, Bluetooth, gigabit ethernet, a FaceTime HD camera, four USB 2.0 ports, a FireWire 800 port, an SDXC Card slot, audio in and out jacks, and built-in speakers. A Thunderbolt port is also included.

Configurations: There are two 21.5-inch iMacs. The first 21.5-inch iMac has a quad-core 2.5GHz Core i5 processor, a 500GB hard drive, and a 512MB AMD Radeon HD 6750M graphics card for $1199. The second 21.5-inch iMac has a quad-core 2.7GHz Core i5 processor, a 1TB hard drive, and a 512MB AMD Radeon HD 6770M graphics card for $1499. Each 21.5-inch iMac has one Thunderbolt port.

There are two 27-inch iMacs. The 27-inch model with a quad-core 2.7GHz Core i5 processor, a 1TB hard drive, and a 512MB AMD Radeon HD 6770M graphics card costs $1699. Then there’s a 27-inch iMac with a quad-core 3.1GHz Core i5 processor, a 1TB hard drive, and a 1GB AMD Radeon HD 6970M graphics card; it costs $1999. Each of the 27-inch iMacs comes with two Thunderbolt ports.

Performance: The four 2011 iMacs are considerably faster than the systems they replace. The $1199 21.5-inch iMac was nearly 24 percent faster overall than last year’s entry-level 21.5-inch iMac, which had a dual-core 3.06GHz Core i3 processor. The $1699 27-inch iMac was 25 percent faster overall than last year's 27-inch iMac with a dual-core 3.2GHz Core i3 processor. The $1999 27-inch iMac was 16 percent faster than the previous high-end standard-configuration iMac: a 27-inch quad-core 2.8GHz Core i5 model.

If you exclude the $4999 12-core Mac Pro, the $1999 iMac ranks as the fastest standard-configuration Mac. In fact, all of the iMacs except for the $1199 model compete very well on performance when compared to the Mac Pro.

buying advice: The $1199 21.5-inch 2.5GHz Core i5 iMac offers the most bang for the buck. If you want top performance, then go for the $1999 27-inch 3.1GHz Core i5 iMac. In fact, if you want a computer for heavy-duty processing work, consider an iMac over a Mac Pro. The only difference between the $1499 iMac and the $1699 iMac is screen size; they have the same components.

Oh, the Mac Pro. Apple hasn't updated this workstation since August 2010. Rumor has it that Apple may stop making the tower Mac. But for now, it's still available, and it's still a solid computer for the most demanding users.

The entry-level Mac Pro features a quad-core processor, while the top configuration has 12 processing cores. In between is a Mac Pro model with eight processing cores. All the standard-configuration models feature a 1TB ATI Radeon HD 5770 graphics card, a 1TB hard drive, four hard-drive bays, four PCI Express expansion card slots, four FireWire 800 ports, five USB 2.0 ports, two independent gigabit ethernet ports, Wi-Fi, Bluetooth, and audio in/out jacks. The Mac Pro is the only Mac that is not equipped with Thunderbolt.

Configurations: The first Mac Pro has a quad-core 2.8GHz Xeon Nehalem processor and 3GB of RAM. It costs $2499. The second Mac Pro has two quad-core 2.4GHz Xeon Westmere processors and 6GB of RAM for $3499. The third Mac Pro model has two six-core 2.66GHz Xeon Westmere processors (for a total of 12 cores) and 6GB of RAM for $4999.

The Mac Pro has a ton of build-to-order options. You can add more RAM—up to the 16GB limit for each Mac Pro. Apple fills only one of the four hard-drive bays with the standard configurations, but gives you the option to add more hard drives or solid-state drives, and even to configure them as a RAID. You can also add a second SuperDrive and upgrade the graphics card. A complete list of options is available on the Mac Pro technical specifications webpage.

Performance: The Mac Pros excel when running software that takes avantage of multiple processing cores, such as high-end video-editing programs, 3D graphics applications, image editors, professional audio software, and so on.

But with general, everyday tasks (emailing, Web browsing, and running office applications), the Mac Pro performs on a par with the iMac. In our benchmarking tests, the $1999 27-inch iMac with a quad-core 3.1GHz Core i5 processor actually outpaced both the $2499 and the $3499 Mac Pros overall; however, when running applications designed to use multiple cores, those two Mac Pros were faster than the $1999 iMac.

buying advice: The Mac Pro is ideal for the most demanding user, one who uses high-end applications and wants hardware expandability. Yes, the machines are expensive, but they're well worth it for professionals, and they’ll still be very usable four or five years from now. If you don’t need expandability but still need speed, consider a 27-inch iMac with a quad-core 3.1GHz Core i5 processor
