I wanted some additional info on the new intel chips that will be in macs in the future. Will the new chips be a big step foward for someone like me (surf the web, email, itunes) The G5 chips were 64 bit. I am not sure what that means other than additional memory. Will there be a big gap in performance between the current chips and the new chips? Will software companys stop supporting 32 bit apps for 64 anytime soon?
