confirmed Blackberry user here, and I'm looking forward to seeing what they pull out of the hat. By rights Windows Mobile and Symbian should OWN the smartphone market, but they both dropped the ball. Windows mobile just didn't advance enough for normal users (i.e. Not Us Lot), and Symbian's wheels appeared to fall off in about 2004.
I'm due for my next upgrade when these are due, so I would like to see what they come out with. Might move off Blackberry unless the 9800 is actually as nice as it appears to be.
