I got the 13" Macbook Pro 2.53GHz with 500GB HD but I have only taken it out of the house twice!!! I also may be taking it to high school on August but that is not necessary. My macbook was $1595 at the cost of portability do you think I would have benefited from the more powerful iMac? (also I play COD4 and Quake Wars on my Macbook, I would have got the second GPU on the iMac)
