The touch screen does look smooth. Notice there is little lagging even in 3D and how fast Quake closes and streetview starts. That's cool. The interface is bloody fast at least on this device. All my Nokia's including N95 are laggy.
I am really looking forward to an android phone. Hopefully the hardware design will be done as well and not be ugly bricks.
Nokia is the one who should be worried about all these developments. They have been sitting on their ass for too long and giving us crippled phones in some way or another. Apple and Android do threaten their relatively easy leadership so far for the simple reason they have not innovated much and not fast enough.
Their feature centric view, drip drip marketing strategy misses the user experience part of it which means even if you have 3g, GPS and stuff you really can't use it to their potential because they haven't thought about the user experience part of it, the screens are way too small, memory is too little etc.
I for one love the iPhone SMS feature, that is the sort of small but thoughtful innovation that makes a huge difference to the user interfacing with the product and these are the sort of things Apple is so good at. Hopefully Google will raise the bar and deliver an outstanding experience.
. Street view 3d however cool that sounds and looks might not be practical unless we have a solid 3g infrastructure in place.
