I tried out a couple of the new MacBooks at an Apple Store yesterday and with both there seemed to be quite a bit of vibration coming through the palm rest. Does anyone find the same thing?

Maybe it was something about the building you were in? Were they doing construction outside? This might sound stupid but it's possible. Haven't read about this problem before, and it's good to try to eliminate red herrings before they reach mini-meme level like the "flaking" thing...
