Surface Pro is a full-fledged Windows PC, of course, and can run most Windows 7 apps. But it's also a multitouch tablet that's optimized for apps downloaded from Microsoft's Windows Store. According to MetroStore Scanner, a third-party site that lets you search the Windows Store from the Web, there were nearly 42,000 applications in the Store as of February 8.
The number of Windows 8 apps is rising steadily, but it's still a far cry from the iPad's 300,000-plus selections. Since backwards compatibility is one of the Surface Pro's greatest strengths -- at least to longtime enterprise users running critical Windows legacy apps -- the relatively thinly stocked Windows Store probably isn't a huge shortcoming.
