Small detail I've noticed in the first hour of using my MBP 17": uneven screen brightness.
Seems to be a bit of a common refrain.
Mine has a band of brightness along the bottom (where the dock sits), with slightly varying brightness along the far L & R sides. Kinda weird, but not a deal-breaker for me. I found if I sat back far enough and fiddled with the screen angle, it became less noticeable.
Did a pixel test, and found only 2 pixels that were a little funky -- during regular usage, you absolutely can't tell (i.e. on the desktop background). In fact, the cranky pixels were hard enough to pick out during the test -- I had to really squint and look closely to find them.
Generally, I'm a pretty happy camper. Very stylish machine, very quiet and fast.
Now -- off to mix & edit a multi-track jazz recording using my MBP!
(I KNEW there was a reason why I bought the damn thing!)
