Heres the deal. I own a current revision 15" macbook pro. I'm craving the larger screen (17") because this is my main machine. Portability isn't really an issue as I usually only move from my desk to my bed. I don't really sit at coffee shops etc where it would be a hassle. So would it smart to sell my 15 now and get the 17" or wait for the next revision? If its just a minor speed bump I'm not really worried about it but if it's something that'll be noticeable faster maybe I should wait?
