I have a 2.16ghz 2 gbram 120 hdd late 06' mbp. As of now its 3.5 years old and still works well for my uses (web, ms office, youtube). Already needed to replace the optical drive and battery (haven't even taken the battery out of the packaging because i plan to sell it with a fresh battery). My dilemma is this back-to-school deal in saving $$$. I wont be in college for the next summer deal so i was wondering to sell it now. ALSO, because i feel the resell value will be better. Suggestions? I am looking to go for the baseline 15" mbp.
