It sure seems to have an interesting UI, and its pretty feature rich. I'll be able to play with it at work just as soon as the devices start to roll out, which is pretty exciting.

The phone specs are really high in comparison to whats needed to run Android phones, kinda makes me feel like Microsoft cant really be arsed to optimise the code much, so they're just gonna rely on brute power to get it through.

Speculation though, I reserve judgement untill I get to sit down with it for a couple of hours.
