I got an HTC TyTN once. I hated that phone so much. Keyboard slipped out, which I guess worked. It was the phone that made me religiously stick with Apple all this time.
That is interesting, I had a TyTN II and miss it to this day. The keyboard was pure bliss, the software was all there (browsing, messaging, photos, calendar, cool games - everything I now use my iPhone for). It had a nice chunk to it and made a cute sound when you slid the keyboard out. You could even run Android on it thanks to some nice people on XDA.
