Trying to decide between the higher end 15 inch or the 17 inch Macbook Pro. Money doesn't matter to me (though I'm not upgrading them). I'd like to play just team fortress 2 (preferably at native ?), but other than that I don't care about game performance (i guess i'd be willing to sacrifice it). Is the 17 inch slow since it's so big (like are there any problems with websites)? Is it too clunky?
