I was having problems adjusting from my 8320 trackball to the trackpad in brickbreaker, but I found that you can actually go into the brickbreaker options and adjust paddle movement and sensitivity and it makes it all better.
I haven't had any problems more then the usual how did that miss the paddle issue. But I have noticed that it seems to run slow like the phone is under some heavy data stress when it isn't.
It's really kind of depressing. I used to be addicted to brickbreaker, and have maybe played it 5 times since the 9700's release. The response of the trackpad is not nearly as accurate as the trackball (in this application)
So now, I just waste my time losing fake money in the poker game that came with the phone.
I moved on to poker. I agree once you have gone through all levels a couple times doesn't make me play anymore. I do love the poker. I order my 9700 yesterday so I don't have yet still on the 9000.
