I hope this is not a stupid question, I've searched various threads on this forum but could not find an answer. I am considering a TP2 (currently a TP owner) but am intrigued by the HD2. Except for the lack of keyboard, what are the differences between an HD2 and TP2? Does the larger screen make an on-screen keyboard usable enough that you don't need the physical keyboard? I use my keyboard on my TP extensively but that's because the on-screen keyboard is just too small for my oversized thumbs.
