Target market: Windows Users + Android Tablet owners
Windows 8 hybrid devices are perfect for those frustrated by lackluster Android offerings (nexus 7 excluded....but not really). Take a look at the Transformer Prime, which was setup to make it seem more like a usable PC, in addition to being an iPad-like device. The problem is that the platform was not made with desktop operation in mind; and everything feels a bit tacked-on.
Tablet apps on Android aren't so numerous that Win RT/8 can't be an alternative. I know my android tablet is hovering on the edge of the trashcan, waiting for the Surface RT to push it in.
