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.

Microsoft's Patch Tuesday for April to address Windows 8 vulnerabilities

One patch may be the first ever for Web Apps 2010

Windows 8 and Windows RT are subject to critical vulnerabilities that will be addressed on Microsoft's Patch Tuesday next week, both by virtue of supporting Internet Explorer 10.

The bulletin for the vulnerabilities addresses similar problems in all versions of Internet Explorer from IE6 through IE10. That means affected operating systems include XP, Vista, Windows 7 and Windows 8.

"This is one of the few bulletins this month that has a critical impact on the current code, hitting Windows 8, Windows RT and Windows 7 with a critical remote code execution issue," says Paul Henry, a security and forensic analyst at Lumension. "We recommend that this bulletin be your first patch and you should update Internet Explorer while you're at it."

Browser vulnerabilities can lead to exploits being downloaded from infected websites that allow executing remote code on affected machines. The vulnerability affects all Windows desktops, "making it very much the bulls-eye for would be attackers," says Alex Horan, a senior product manager at CORE Security.

There is second critical bulletin this month that affects Windows XP, Vista and Windows 7. "This bulletin does not affect Windows 8 or RT, but will likely still impact a lot of people because many have not yet upgraded to those operating systems," Henry says.

Seven more bulletins are rated important, which means they could be exploited to compromise user data. One of those affects Windows Defender, which is part of the security package in Windows 8 and Windows RT. "Windows Defender is an important security component for the new operating systems, so it's a little concerning to see it impacted here, even if only at an 'important' rather than critical level. If you're running either of those systems, I would patch this important bulletin first," says Henry. It's not clear what the issue is with Windows Defender.

Another bulletin rated important "may also represent one of the first reported vulnerabilities for Microsoft Office Web Apps 2010, which would be significant in and of itself," Horan says.
