I have the new 17" Penryn w/ HD Glossy... First there was the creaky hinge, then the popping noise in the left speaker just before any sound. I was able to deal with it and wait for a vacation to put it in to apple for repairs. Next the track pad button was sticking and made a clunking noise when it gave. That started to make me think about putting it in the next Monday. Before I had a chance to ponder that, I had an error message that my mail index was corrupt and to restart mail. The forever beachball, manual power down, and nothing but beeping.
Apple Care is now sending me a brand new unit. So for this 17" owner I am on number 2.
