Hi, I have a 4 years old MacBook Pro 13'' mid2010, and it started to crash (during start-up, or a few minutes after it started) and showing a grey screen. Took it to the Apple support centre ... and the logic board failed!!! The 2-years warranty is long gone, and for a new logic board they asked more than half of what the computer costed! Is this common in Mac computers? I was expecting to still keep it for one or two more years before buying a new one. But now I really don't know if I should go for a Mac again. I mean, one would expect a computer to last more than 4 years, wouldn't one?
