After my iPod problems, Applecare got my iPod picked up, couldn't fix it, and sent me back a new one...I must say their service was excellent from the very beginning...
Same here. I got my replacement in only a few days after I sent it in! I was pleasantly surprised. 'Course, now that I only have 4 months left in my limited warranty, this one will die in the 5th month... I sure hope not...
