This is my second Mac, and my first apple notebook. I bought the 2.4 Unibody Macbook pro about 3 weeks ago and managed to get 7 of the screws required to upgrade the ram out just fine. Unfortunately I stripped the head of the last screw. Spent 30 or 40 bucks buying screw drivers to try to get the screw out to no avail. Finally just took it to the Apple store to see if they could do anything. The guys apparently cut off the bottom case and/or stripped screw and replaced the bottom part of the case and put in new screws. They didn't have to lift a finger on this one, but they did an awesome job except for the minor cut in the battery's "skin" from their cutting tool. Just thought I'd share.
