sorry if this has been discussed before--ive been readin around on this site for awhile now and i havent seen anything about this yet. i plan on buying a 17" macbook pro for college. theres a chance i'll be stuck with it and only it for all 4 years (though im gonna start saving immediately to get a desktop hopefully before i start my 3rd year). i'll be using it for gaming, movies, internetbloggingetcetc, and whatever a graphic design major throws my way. school starts around august 17th. ive never used a mac and id wanted to order the mbp as soon as possible so i could adjust. but. all this talk about merom has obviously changed things. id like to wait, but since its only gonna be released in august, and it would take awhile to get the laptop in, thats cutting it *really* close. ive heard one person say it would be ..easy to upgrade (i dont know much about this stuff, sorry =\) later on, and others say itd be impossible. could someone clear that up? and, most importantly, would it even make any difference for me? for the things i'm gonna be using it for, will it really be a big deal for me to *not* wait? would i even notice the difference?
