Okay, so as of now, we're all (hopefully most of you all) are waiting for the MBP update like me. I can assume the updated ones should have 2.5" HDs. If I were to manually input an internal HD, is this as easy as installing RAM yourself? If so, what is the largest and most RELIABLE hard drive out there that is 2.5" and can fit in a MBP? I am a person who NEEDS space (since I am 3/4's filled up with my 320GB Seagate External Hard Drive). I don't mind paying online. Thanks for any help.
