Want to try out the Windows 8 Metro interface on your Android tablet? Splashtop apparently has a solution. The company previously released a Windows 8 Metro testbed for the iPad back in April, and now it has one for Android devices, which is available in the Google Play Store. You'll need a PC with the Windows 8 Release Preview installed, but once you have that taken care of, you'll be able to poke around Microsoft's new touch interface on any Android tablet
