So A guy has a black macbook for 800 dollars. 1.5 years, 1 GB of ram 80 GB of memory. I'm going to be using it as a companion to my iMac. Do you think this is a reasonable price or should I shoot for lower? The only problems I can see are the brightness sometimes randomly adjusts but I don't know if that is normal and the click button is faulty uniess there is something between the battery and the round thing under the battery but above the mouse if the macbook were flipped over. Any suggestions?
