I am looking to buy a ibook. Or for that matter any affordable laptop mac under 500 dollars. I see that there are large amounts of ibooks on ebay. I would like to run itunes and wi-fi on this comp. I also have a pc so the mac will mainly be used for media perposes. I was wonding also if any ibooks have imovie installed and can adiquatly run this program. If someone could tell me generaly the minimum specs that I should be looking at I would greatly apresheate it.
