Hi y'all, So I've decided to take the plunge and get a MBP for christmas instead of waiting for any updates in january. The main thing that bothers me tho is that i kno that 120gb HD space is gonna be filled up quite quickly for me. For now i was gonna get portable hard drive. I would like to be able to upgrade the hard drive some point in the future but obviously this means opening the MBP up. I've heard mixed things about this. Some people say that it voids applecare, and others say that its against some sort of regulation and should not void the applecare. I was hoping if someone knew the definite answer? P.S. I need to buy it from instore to take full advantage of my university ed discount and so therefore can't simply BTO the hard drive sadly. The next model up is also too expensive for my budget.
