I did it! 1GB stick RAM : $120 - $25 mail-in rebate; $95 Comp USA install genius: $30 Time saved opening & running apps like iTunes, iPhoto, Photoshop, M$Word , all at the same time: PRICELESS!! : If you're wondering if it's worth getting rid of that 256MB, definately YES imo. Like a new machine! I strolled by the 24" iMac on the way out, now I have drool all over myself... But more RAM! Yay!
