yeah typing on that BB storm is really hard.(tried er out at the store) When you touch the screen the whole thing goes down as a button so you feel the click or whatever.. So you almost have to do 1 finger typing, if you try to use 2 fingers you have to go so slow to wait for the screen to pop up from the first letter pressed it makes typing really hard.
I'd go touch pro personally since its very similar to the titan but faster.. BUT as I have a year left on my contract I can hope for something worked FROM the TP but even better.
