Since i got it, it has given me nothing but problems. The hard drive makes funny noises (popping), The case is misaligned, i have a few dead pixels, plastic around the screen is coming off, applications keep crashing, it can't back up my data. I only got it on wednesday. Is this just a very unfortunate model or are others having these problems. I bought a macbook for reliability, instead it got this. I have to say though, apple is very good and is replacing it on thursday, hope i don't have that same problems, it was not even a week old. What are your worst mac experiences?
