Greetings...Happy Independence day! My 15" MBP is going to be officially off the 1 year AppleCare that came with the unit on 7/9/2008 and I need advice on: 1). I added a 7200 RPM drive the the MBP...Does that void any applecare warranty (either the base or any extended warranty I would purchase)? I don't want to purchase the apple care and then find out it is voided because I added a bigger/faster hard drive. 2). The MBP is only use 2 hours a day on average and is not really moved around alot. I have not had any problems with the unit or any heat problems. I usually do not purchase extended warranties because I usually go off the premise that "If it does not break in the 1st year...it is probably not going to break". Since I have not had a lick of problems with my MBP and my Alu iMac...I am questioning the need for AppleCare. Advice and comments welcome.
