Using a Noka 920, and this is my first smartphone. I didn't even 'text' with previous cell-phones.

After 40+ years of using a full-size KB (yes I am that old) I find this thing impossible to use, and am amazed that people happily accept it as a workable solution.

One of the things that I do find baffling is that in landscape mode, WP does not use the full width of the screen for the KB display, and so the keys are not as big as they potentially could be.
