How many people here use a TP2? Mine sometimes types the wrong characters. Seems to happen when I hold the shift key down. I don't know, but it's already on the edge with me, and if it is typing the wrong stuff on top of that...time for something new. Unfortunately there isn't a lot better feel out there where Mac is concerned.
(For those who haven't been watching...I'm addicted to my special apple keys that do things like eject cd and volume up and down.)
