To me that keyboard looks like a slightly more cramped version of the N97 keyboard (the layout is the same, but the buttons are just smushed together).

As I've heard nothing but disappointment about typing on the N97, I don't find that comforting; although to be frank, I found the keyboard on the N810 to be unuseable (which was one of the main reasons I got rid of it after a few weeks and went back to my N800).
