I have had the storm...hated it.
And I'm on the other end of the spectrum. I have the Storm, and I love it.
I have only had one problem, where the camera locked up for some reason, and I had to take the battery out. Other than that, no problems what so ever.
The one thing that I did do, when I got it, I had done a lot of research, and was leaning toward the Tour, but I couldn't press those little buttons in the store. The sales girl showed me about turning the storm on the side to get a full QWERTY keyboard, and also told me to take it home for a week, and get a list of questions, then come back in for training.
They stood there for about 45 min and told me all the ins and outs of using the phone...little tricks, like closing apps, rather than just "backing" out of them. That is what causes it to lock up, and I haven't had any problems....
