Believe it or not, there are still people out there that prefer hardware keyboards. If Moto makes this available worldwide and not only on Verizon, it could be a pretty popular phone (if they don't cripple it too much, that is).
I went from a droid 3 to a galaxy note 2, thinking I'd be fine with a screen keyboard being i'd have enough space. I would prefer a physical keyboard still. I'd buy a 5"-6" phone with a slide out keyboard.
