I encourage to watch at least the first 10-15 mins of the presentation (then the marketing speech takes over).
I agree on the thoughts of Marko Ahtisaari how touch screen mobile devices are still (on average) somewhat awkward to use. In my opinion closest cousin to N9’s UX is WebOS. Although doomed to walk in the shadow of Android and iOS, N9’s Meego Harmattan and WebOS are both representing the 2nd iteration of touch screen UX design.
It is sad that the future of these OSes looks very murky.
