Well I had my MBP for 2 months now and Im enjoying it more as time passes. This is my first Mac that Ive owned, and after using PC's for years the transition was hard. I have a 15"1.83 w/ 80gb and 2gb ram. Now im thinking whether or not I want to get the 15" 2.16 with better specs. Being that I can get the 2.16 15" for $2k brand new do you folks suggest I make the upgrade, or is it worth it? Will I really experience any speed/performance difference. Im open to suggestions.
