The elephant in the room

Surely Microsoft's big problem is the iPad. They need a tablet OS that can compete. If they don't get one soon the desktop will be all but irrelevant to consumers because they will be caught in by their own mantra. 'Users like what they are used to'.

Why would anyone buy a WinArmPad? Is it ubiquitous? No, everyone else has an iPad. Is it familiar? No, it looks and feels different from existing Windows. Does it have the familiar apps? Not yet, and it won't run existing Windows programs either. Is it cheap? No, Android + Arm = cheap. Unless of course Microsoft subsidise them heavily until they have a dominant market share as they did (do?) with xbox. They have deep pockets but even so they could be betting the whole farm on a strategy like that.
