I think this UI looks really clean, understated and seems like it could make better use of the screen (freeing up space by what looks like halving the top bar.)

Hopefully we'll see some shots of the notification system and so on.

The 'lifestream' looks like it could do with a little work, but other than that, I'm quite happy with it.

The netbook UX was not as appealing, it is just the moblin UI
