Just curious if you all have some opinions / suggestions for me. I have a 15" MacBook Pro (2.33Ghz, 2GB Ram) with a 120GB 5400 rpm hard drive. I am thinking about upgrading the drive to a 200GB 7200rpm drive (more speed, more space) and need to use a service to do it as to not void my AppleCare warranty. There is a place locally that can do it, but it may be more expensive than the online ones. Still checking on that. I found a few places that do it so far (techrestore.com, macservice.com) - has anyone used either of these (or another one)? If so, how did it go? Also, if you have a similar model as me, did upgrading to a 7200rpm drive have any negative effects? I want to make sure the extra heat (if any) won't have any effect on my system. Thanks!
