Pros: None.

Cons: This is a used machine, with no indication of having been refurbished, other than the hard drive was either wiped or erased. The machine that I received behaved as follows: On initial power-up, the machine made it most of the way through the initial setup sequence before powering down. Plugged the machine into power and started evaluating. The machine kernel panicked while running software updates. Turned the computer on again, finished software updates, and then the display blacked out. Force restarted computer, and it kernel panicked again. Stick with an Apple refurbished machine. These aren't worth the risk. Now I have to pay for shipping, and they'll probably ship me another one in the same condition... :-(
