Why a 7-inch Surface tablet would be a mistake for Microsoft

Rumors have begun circulating that Microsoft is working on a 7-inch version of its Surface tablet. I'm not convinced the company should even bother.

For the past couple of weeks, the web has been buzzing with rumors and speculation that Microsoft is working on a 7-inch version of its Surface Tablet. There has been no official word from Microsoft, of course, but if you look at current market trends, introducing a smaller tablet would seem to make a lot of sense. The popularity of the iPad Mini, Kindle Fire and Google’s Nexus 7 are clear indicators that consumers are interested in smaller tablets, and Microsoft surely wants a piece of the action.

Microsoft is in somewhat of a unique situation, however. Not only does the company already have a slew of hardware partners it probably shouldn’t anger any further, but it technically has two mobile operating systems to choose from, Windows RT and Windows 8. Although Windows RT and Windows 8 look similar, the former lacks compatibility with legacy x86 Windows applications, while the latter has somewhat steeper hardware requirements to run smoothly. And therein lies the rub.

A 7-inch Surface Tablet would be a tougher sell than the original.
If history is any indicator, and Microsoft is actually working on its own branded 7-inch tablet, it will most likely run Windows RT. Unfortunately, Windows RT hasn’t exactly been the darling of consumers or the tech community. In fact, many experts are calling for Microsoft to just kill off RT altogether and focus solely on Windows 8 for tablets. With Intel’s current x86-compatible SoCs already offering better performance and similar battery life than the ARM-based alternatives for Windows RT, it doesn’t make a whole lot of sense to continue expending resources on Windows RT. And if rumors hold true, Intel’s upcoming Bay Trail-based SoCs should only push RT further into oblivion.

The alternative is to produce a Windows 8-based, x86-compatible, 7-inch tablet. But I can already hear the tech press complaining now. They’ll say things like “Desktop mode is useless on a 7-inch tablet,” “You’ll be paying for features you won’t use,” and “There aren’t enough Windows 8 apps,” and so on. Whether everyone feels the same way or not, information and reviews full of caveats about a product don’t exactly instill consumer confidence and foster success.

Microsoft has taken such a beating lately that I’m of the opinion they shouldn’t bother with their own 7-inch tablet. Unless they hit an absolute home run on the hardware and market the device creatively alongside an enticing software promotion, there’s little chance the product will be well received. Microsoft should focus on bettering Windows 8 and its successors, and let its hardware partners introduce new tablet form factors.

BlackBerry details extensive security protection in BlackBerry 10 OS

BlackBerry 10 OS is distinct from previous BlackBerry OS in that it can separate personal from corporate apps

The recent release of the BlackBerry 10 operating system sets the stage for a security evolution as well, according to Alex Manea, manager of security services at BlackBerry.

For one thing, the BlackBerry 10 OS is distinct from any previous BlackBerry OS in that it provides a way to separate out personal applications from corporate-designated ones by using a capability built directly into the OS called Balance. Manea says this "partitions the phone into two spaces, a workspace 100% controlled by IT, which can delete it without interfering in the personal side" and represents a way that businesses can support the bring-your-own-device (BYOD) trend by allowing employees their personal space on BlackBerry, too.

And although this BlackBerry Balance dual-partition capability for BYOD is not available for Google Android or Apple iOS devices, BlackBerry management can support these non-BlackBerry devices, says Manea, adding it involves adding a specialized app to iOS and Android devices to do that. Through use of the server-based BlackBerry Device Service software for BlackBerry 10, businesses can manage Android and iOS devices as well, though not Microsoft Windows Mobile, he says. Management capabilities include features such as lock, track and wipe.

BlackBerry is also working on what's known as a "containerization" type of technology for applications that could also be used for iOS and Android that would allow IT managers to place something akin to a container wrap around an app based on IT-based policy decisions.

BlackBerry 10 is also supporting data at rest and in transit through encryption, with the ability to swap out encryption algorithms.

But in addition to new features like Balance, the advent of the BlackBerry 10 OS has set the stage at BlackBerry to evolve the basic security strategy related to present and future smartphones and tablets. For example, BlackBerry recently established a partnership with security firm Trend Micro to assist in vetting apps against malware thorough the cloud-based Trend Micro Mobile Application Reputation Service. And in another partnership with Germany-based Secusmart GmbH, BlackBerry is creating a specialized encrypted mobile voice capability for BlackBerry that would be used by the German government there.

These kinds of projects are widening the perspective on what BlackBerry might undertake in the future as pertains to the BlackBerry 10 OS as a platform, including potentially coming up with a set of security APIs that third-party vendors could build to, such as the kind of anti-malware hooks which they don't have today. There has historically been very little malware aimed at BlackBerry because of its core design being highly virus-resistant, but it is growing.

Manea says as BlackBerry considers what it might undertake in terms of growing its security capabilities with BlackBerry 10, it's evident that the firm is more open than ever before to the idea of exploring projects, partnerships and possibilities.
