My wrists hurt too!
Yes, I suffer from the sharp edges problem on my macbook pro, and also the hairs on the underside of my wrists get painfully caught in the small gap between the edge of the top panel and the side edge.
I too am flabbergasted that mac would design such an unergonomical machine. How hard would it have been to have a nice smoothing off edge like pretty much every other laptop I've ever seen. It seems like a symptom of something I've suspected about mac for a while - trying too hard to be trendy at the expense of useability.
I like the machine, in that it will run logic pro nicely with my soundcard, and I like that it's based on linux, but come on! Maybe get a few test users to actually use the product to see if it has any design flaws? Grrrr...
