[BVI Beach Bum]

I am in the second week of my ownership of the Curve and really like it, but the trackball seems to be very loose and is skipping around when I use it. I tried playing with the sensitivity, but no real improvement. Also, the keyboard seems loose when typing an email. My buddy's 8800 seems rock solid compared to my Curve, and I seem to like his keyboard better. Any thoughts? Do I have a bad unit or should I switch to the 8800 as it might suite my hands better. The only problem I have with switching is that I really like having a spellchecker and the call quality on my Curve is better than any other BB that I have ever used and I don't want to go backwards in that regard. The camera is nice to have, but I could live without it. PLEASE help!
