Is this a good deal? I can't remember now if it 1000 or 1099. It's for a 20" 512mb, I'm not sure on the hd and its the coreduo(vers 1) processor. I don't have a lot of details, but is that a deal worth checking out. It's up at our university bookstore. Its a close out deal i guess. My next question is...How big of a speed increase would I get if going to the core2duo? Example - convert a song off cd in iTunes or more importantly burn a 2 hour movie and compress in iDVD?
