Okay, so my girlfriend has the first revision MacBook. It's had quite the history with issues over the past few years. It's had the discolored plastic... but I'll excuse that one since it's purely cosmetic. However, aside from that, she's had two battery replacements, a melted magsafe, a SuperDrive that scratched rings into discs, a non-functioning ethernet port, a hard drive failure, and now what looks like a logic board issue causing random shutdowns. We've sent her computer in for repair/visited the Apple store for battery replacements at least once every three months or so in the last two years. As an owner of an iMac G4, PowerBook G4, MacBook Pro, and a mac pro, I can say that I've never seen this many problems on a single mac. Last time we called in, it was the hard drive failure (which I believe happened in April or May) and I asked the person on the phone what Apple's standard procedure for an outright replacement was. He said something along the lines of "We usually only offer one after a computer has had a certain number of qualifying repairs" (which I'm assuming means stuff like discolored plastic doesn't count--nor should it). Then he said "Are you asking for a new computer?" This may have been a situation where he couldn't offer me a new computer, but if I demanded one, they could give it to me. I didn't say I wanted a new computer, but I was simply asking what would make one eligible for a replacement system. But now I'm at the point where I think this system need to be completely replaced. It's obviously not a functioning computer. When it can't be used for 3 months without something going wrong, this is not a computer that any work can be done on. If your computer can suddenly shut down in the middle of an online test, or your hard drive fails in the middle of writing a 15 page paper, you may as well not have a computer and just store everything on a flash drive. Would this latest experience in the string of problems be enough to warrant a replacement system?
