I'm impatiently awaiting the purchase of my first mac, but can't help by wonder at the number of posts on this site where a failed logic board has been the problem. Granted I'm on a mac forum site where you'll see more complaints than compliments, but I wanted to get an idea from you longtime mac users how often this happens. In the past 15 years, I've never had a laptop or desktop fail due to processor or anything like that. Well, actually I had a processor fail when I touched a screwdriver to it without first grounding myself. The other issues I've had were 2 hard drive failures - that's it. So how often do these logic boards fail on macs anyway? Thanks.
