bought a black macbook today.
no whine/moo/sound whatsoever. in fact im concerned that the fans arent coming on often enough!
out of the box i put 2gb trancend RAM in, did a clean install of OSX (to remove printer drivers, etc etc.) and ran system update.
a couple of crashes so far... will have to run memtest overnight.
only real concern is the heat from this thing. its idling around mid 60 degrees, and under load up to 80 degrees C.
its really really hot on the underside (left) of the unit, and also above the keyboard.
other than that issue, no real problems.

EDIT - completely fogot to state that this is a WEEK 25. purchased from apple online.
