I've got a MacBook Pro, and it's so dog slow, it's pretty pants really. I've got a CoreDuo, and the screen fades out, it floats around 70ºC and above usually, it makes a really irritating high pitched whine, it goes to sleep and then wakes up again later while in the bag & second skin with the lid down (not software related, overheats and drains battery) and there was a dent just by the PC card slot, which has caused the case around it to bulge.
I'm hoping that when I take it over to Apple in Cheltenham they give me a replacement. To me, that seems like more than 3 seperate faults...
