> I can't figure out what usability case would mandate a trackpad that large.
I couldn't figure it out either. Did they have a bunch of focus group feedback saying "this trackpad is too damn small... moving my wrist 1/4" to touch the trackpad from a resting spot is way too much work, I'd rather have my wrists touching the trackpad"? That's the only feedback I can see them getting to justify it. That or... it's a general trend towards the ios-ification of mac, and pushing towards "touch interface" for everything (except, of course, on the actual screen).
