I own a Powerbook 1.67GHz currently with 1 gig of Ram. I am wondering if 2gig will make my laptop "snappier". What I mean by that is, panels and applications opening faster. An all around quicker feel I guess. I just feel like there is a slight pause after every command. Is this slight pause a "mac" thing? Does anybody here have 1st hand experience going from 1gig to 2gig's? I do have the 7200 rpm harddrive, I use Photoshop and Flash. No games or Video Editing. If you guys think its a somewhat noticeable difference, I will head out and buy it today.
