I am considering a 200GB 7200rpm drive for my new MBP SR 2.2 and have downloaded a couple of tutorials/videos on how to do it. Seems fairly straightforward. Has anyone here done it and is it something I should try or take it in. I've always built my own PCs and I've disassembled a Dell laptop (not too worried about messing the old laptop up) but I know user caused damage is not covered so I am a little apprehensive. Any advice?
