I've just returned from the Apple store with my third(!) MBP SR! Fingers crossed that nothing is wrong with this one. This is my first mac, and the experience has not been very pleasant so far. I don't know if I'm just being picky, so I thought I'd ask everyone first before I contact Apple for the 137th time. Does anyone else notice that their spacebar makes a different sound when hit. Sorta sounds like it's loose, but it's not. All other keys are pretty "silent". Help! I don't want to go back and get a 4th MBP, but damn it, this thing costs $2,400 so it better be damn near perfect! The warped display I can live with, but I use the spacebar everyday! Enough rambling. Share your experiences. Much appreciated!
