I bought a unibody, 2.4GHz MacBook a few days after they were released. It was great, but after around 2 months the 'y' key kept coming off, and there was also some sort of smear inside the screen.
So I take it to Apple, and they don't have the part. Okay, understandable! They phone me telling me they have a new top housing ready, and a new display. I hand it in, and 8 days later I get a call saying "Hi Kyle, we haven't started working on your machine yet - we think that the smear is liquid damage, you're own fault". I'm thinking: hmm, okay. They said water got through the Apple logo and so they aren't willing to replace it. I guess, given the fact that I did once spill a tiny bit of water on the front of the machine that this was plausible.
Day 9, and I get my MacBook back with a new top housing and a pretty great clean too. I come home, and it isn't charging. It was before I handed it in. So I book an appointment, take it down and they say it needs a new logic board. They don't have in stock - I'll let this slide too, understandable - but they say they have put it on high priority.
That was on Thursday. I get a call about 20 minutes ago saying "Hi Kyle - you're macbook is fixed and ready to go. We checked it and it is working. Come down and collect!" - Great! Well, not so great because 10 minutes later they phone again: "Hi Kyle - sorry to phone you but there's an issue with your microphone now. So we'd appreciate it if you didn't come down and waited a few more days".
I'm having some serious bad luck. -sigh-
