So I bit into the hype and recently purchased an apple wireless keyboard and that evil bar-of-soap thing apple makes for a mouse. Couple of hundred dollars later and this is where I begin to worry about RSI. Go figure.

Don't get me wrong, this apple mouse is genius and looks pretty as hell, but my right wrist feels tired after a full day's worth of work, so i'm thinking of switching.

Anyone out there use a trackball? is this worse? should I get a super-ergonomic mouse instead?

I've seen mouse-trackball combos but am not sold, they still elicit the same end-finger behaviour detrimental for RSI, right?

I also have a wrist-rest mousepad, but couldn't find one suitable for my keyboard. I've even considered having a small touchscreen where the mousepad should go, no mouse (or alternatively, a usb trackpad).

Just looking for ideas, is the trackball better than the mouse?
