Fairly convincingly nice and elegant UI. It clearly owes a lot to iPhone and iOS, although that is not to suggest that it improves on iOS, and certainly not on iOS 5, although the maps do look good.

The history feature looks like a privacy nightmare. One swipe away, and someone who borrows your phone for even a moment can immediately see everything you've been up to. Where is the empathy for the user? BTW if I let someone borrow my phone, that means I have already unlocked it for them, but it doesn't mean I want them to have one-swipe access to everything.

As an aside, next time they should consider having a more likable and less arrogant-looking person do the talking, and without (apparent) overdubbing. It came off as slightly creepy.

I'd love to play with one, but I don't expect it to make any dent in iPhone. I am curious what other cool features it has that didn't make it into the video... since it's Nokia, we can expect a lot, so they do have my attention at least temporarily.
