For me it's either a trackpad or a trackball. I find that any pain comes from moving my wrist and the Magic Trackpad is large enough that I move my entire arm and not the wrist.

It's great that we have options, so that people can pick what works for them. It is a little sad that Apple is pretty much the only option for an "external" trackpad though.

Back in the 90s I had a 102-key keyboard with a built in trackpad (and dual PS2 connectors to hook up to the PC) that was actually pretty nice—except if I tried using the trackpad when my fingers were damp in which case it was hell. I bought it in anticipation of moving to a laptop (which didn’t actually happen for another 5 years), but it was the first step in my becoming a trackpad aficionado.
