Today, Box announced a tablet-optimized Android app, a PlayBook app (the company's first native app for any BlackBerry platform) and a new HTML5 mobile site. The Android version replaces the company's existing Android app and will work with both smartphones and tablets, optimizing the view depending on the device.

More interesting than the actual app announcements, Box CEO Aaron Levie revealed that the company has seen a 600% increase in enterprise sales regarding mobile. And yes, that's specifically enterprise sales, not overall sales. For example, Proctor and Gamble just became a Box customer based largely on the company's mobile support.

Microsoft has said that iPad-style tablets, generally referred to as "slates," that run Windows won't arrive until the next version of Windows arrives in 2012. This big beast of a WP7 tablet announced at Computex not withstanding, this rules out Windows Phone 7 based tablets. But will Microsoft get left behind if it can't bring a slate to market before 2012?

As we reported last week, Citi analyst Walter Pritchard believes that it's not too late for Microsoft to have a "meaningful" share of the tablet market. Larry Dignan at ZDNet highlights one particular area where Microsoft could challenge other vendors: Microsoft Office support.

Many geeks still mourn Microsoft's stillborn Courier project. For those that don't remember, the Courier was a small, dual screen, hinged tablet that Microsoft officially killed off in April 2010 before releasing. The hardware is dead, but ZDNet's Mary Jo Foley thinks some of the software might live on in Office 15. Some supposed leaked screenshots of Office 15 include a new app codenamed "Moorea," which Foley thinks looks similar to an application seen in leaked Courier videos.

Foley asks "If Moorea brings this interface to life, maybe Microsoft will position Moorea as a 'killer app' for the coming Windows 8 tablets/slates?"
