Here is yet another MBP customer shocked to discover the sharp edge on the palm hurts to use it. I'm not sure what Apple was thinking, its entirely un-ergonomic this way. Resting your palms is in fact most restful then holding them up, particularly while using the track pad. In order to use the trackpad, I constantly find myself with my palm right on that sharp edge, worse yet...the little pointed corner where the notch is to open the lid is right under the palm there too. I swear it feels like it could draw blood someday. The MBP is beautiful to look at, but all those edges should have been dulled, even the slightest bit would suffice. As is they pretty much demand that some kind of shell be used, which of course defeats the purpose of having such a beautiful looking unibody frame to begin with, if you have to keep it hidden away inside a skin.
