I know there have been other posts about this, but I'm really curious if anyone has anyfirst hand impressions of the noticing a difference. I'm about ready to get my first macbook to replace my iMac. I'm going to be constantly using illustrator, photoshop, and bridge in tandem. Additionally I'd like to be able to have itunes, safari, mail and a smidgen of parallels. Also will be using the macbook with a 1600x1200 external display when at home. I understand that if I use up more then 2GB's of ram of course there will be performance benifit. I'm really interested in though, does having 3gb of ram make the system sluggish if I'm using a moderate amount of ram? (things like slow dashboard) THanks a ton, any advice would be fantastic!
