Hi, I am starting college in the fall. I saw Apple has refurbished previous-gen 2.2GHz 1GB white Macbooks for $999. I only use my computer for internet surfing, email, Word/Excel, iTunes, and some light Photoshop use (nothing major, just basic photo editing). No gaming or video editing. My question is this. Do you think I should go for the refurb Macbook now since it's so cheap? Based on my computer usage, do you think it would last me for all 4 years of college? And should I hit up OWC to upgrade RAM or is 1GB enough for what I do? Thanks for the input!
