Hi guys, First of all, some background on my MBP so far: http://forums.macrumors.com/showthread.php?t=706581&highlight=keyboard+key+vibrate Updates: now the damn key vibrates even at 2500 RPM, and a firm press on the key confirms that it's not loose, since I can still feel it vibrating. I feel no such sensation from any other key, at any fan speed. Now, the AASP technician is claiming that "all unibody MBPs have vibrating keyboards". Since nobody else I know has a uMBP, I am at a loss as to how to prove him wrong, since he has probably tried all the display MBPs at his store. I for one can't believe that a $2000 machine could have a flaw as pathetic as a vibrating keyboard. My old $900 Compaq laptop didn't. My old $1300 Macbook didn't. It's most likely just an excuse to get me off his back, but I can't really disprove his claims, especially if all his display MBPs exhibit vibrating keyboards. Could you please help me confirm who is right in this case? Are uMBP keyboards really that lame? Do your MBP keyboards vibrate at any RPM higher than 2000? Thanks in advance for your help. I'd also appreciate further comments/feedback, if you can spare the time. Again, thanks!
