Hi everyone, new to the posts here. I purchased a MBP 15" from the Apple store in June 2007 as my first Mac ever. I'd been a PC user for the past fifteen years. Over the weekend I got the kernel panic gray Restart screen after seeing distorted graphics on my screen. After several cycles restarting the MBP the screen stopped displaying any graphics whatsoever. Both the screen and the backlit keyboard went dark although I had power and could hear the machine trying to boot. Today I saw Apple's post about the NVidia chip issue which appeared to exactly match my symptoms. After speaking with Apple's Genius bar today they tested and confirmed that the NVidia chip is not causing the issue. Instead, they told me I need to replace the logic board. I did not buy AppleCare at time of purchase largely because I'd never had any catastrophic hardware failures with PCs before, and I (naively?) expected Apple's quality to be higher than PCs. Now my confidence in Apple's MBP products is tainted. I wouldn't expect this type of issue on a machine only about two years old. Are these types of quality issues common on Macs, especially logic board replacement issues? At this point I don't believe I can buy an extended warranty, so if my machine exhibits further problems after Apple replaces my logic board I'm afraid I may end up with a $2100 paper weight. And I actually have really enjoyed my MBP up to now. Thus far, my first-time experience with a Mac has been less-then-stellar. I don't know if I'd spend the money to buy a Mac again... Thanks everyone.
