Everything you'd expect from a smartphone - 3MP camera, touch screen, music downloads (DRM-free, from Amazon, not locked tracks from i-tunes), etc
Plus everything you'd expect from google - superfast Chrome web browser, gmail and youtube integration, google Earth, and other apps,
PLUS (and this is why I found it) - integrated satellite GPS, connected to Google Maps, so you get your current position, on an up-to-date map of the entire world, accessed for free.
Knocks i-phone to the kerb, guess I'll get flamed by Apple fans but someone has to tell it the way it is! And Nokia? well, Nok, honey, we've been together for a very long time now, but you have to understand things change sometimes, I just met someone else, hope you understand, maybe we can still be friends, eh?
It's only officially released in USA, but I just had a play with one in a shop in TST - $5,500 - my ship is definitely sinking ... not sure how long I can resist ...
