Just got my new MBP (which took forever to arrive btw), and couldn't resist the temptation to peek inside. However, the top-left screw seems to have misthreaded or something and won't come out. (It just turns round and round). I'm not that bothered since mine already has 4gb of ram and i can still get at the hard drive. Should I be concerned? Btw I've had no other issues like the screen stories going round or the slanted keys, but the trackpad does seem to be dreadful under windows xp. PS 1st post - be gentle!
