I bought my MacBook pro (late 2011 base 15') from amazon warehouse a couple of days ago and it's scheduled to be delivered tomorrow. I know amazon warehouse's 'like new' products have a good reputation around here, but what are the things I should look over to make sure I got a quality MacBook pro.

1. Physical condition
2. Battery cell count

Any other suggestions?..

Non-working keys.

Bad pixels, sticky keys, lots of spinning pinwheels of death, working ports, working bluetooth, good charger, just some of the things I can think of
