I thought I'd share my real world experience with the magic trackpad.
I'm probably going to return my Magic trackpad less than a day with it. It's cool and nifty in certain ways, but it's straining my wrist - I tend to float over it for fear of activating it by touching. I've tried getting used to leaving it on there, but it just doesn't seem natural really. Im then constantly lifting it to navigate, thus restraining it.
Otherwise, I enjoy using it for browsing the web and various controls (Itunes, Iphoto zoom etc). I did notice it was a bit difficult to select things...I finally got used to the double tap/hold to select and drag something (a window, volume slider)
I'm used to Logictec roller ball mouse- this one:

... I've got extra large hands and enjoy resting the palm of my hand on the rear of the mouse and the ergonomics of my hand arced over the mouse accessing the rollerball on the front of the mouse.
On my macbook, I enjoy the trackpad, but I also notice that my palms hang off the front so I don't experience the pain in my wrist.
ANyway, its for some but not for me - very unfortunate really, I'm sold on the idea, but I need a different execution....maybe one with a hand rest on the front! I dunno about that...might be ugly
Oh yeah, as you might've noticed, I don't use my magic mouse either... cool as well, but not for me.... again bad ergonomics....plus I really dig rollerball... dragging a mouse around the table top is so 1990's for me
