Ok, hands up...
...who here actually cares about running Windows on ARM?
I use Windows extensively, and quite like it; but let's face it - the reason for running Windows on anything is the available software. Which only works on x86. Yes, yes, I know there's some promised-land of emulation, but in literally every case I have experienced the overhead has been obscene, driving either the power consumption up or the user experience down.
I just really don't get who their target market is. Want a device that can play video for ages and ages? Get a Linux or *shudder* Android device.
