Wait, so in addition to their crash-prone software, MicroShaft will be building the hardware too? Yeah... count me out. Considering an iPad 2 - for the interface. The whole lack of flash is somewhat annoying, but thus far the UI on my iPhone has been solid, while Android phones I have had previously tended to get wonky pretty quickly.
Last Windows based phone I had was a T-Mobile Shadow. The hardware was great (HTC), but the damn thing took longer to boot up than my laptop. I realize it's been a while, but the MS mobile UI was pretty much crap then, so I haven't even considered anything windows powered since.
