I have just graduated college and a late 06 MBP 2.16 ghz, 120g hd, 2 gig ram have served me well through my studies. I recently had to replace the super drive and battery, and it has slowed down a bit from use. For my needs, i just do a lot of web browsing, word processing, and movie/video watching, might edit my family movies from back in the day to put them on dvd. Should I sell my old 06 mbp and buy the new mbp? In other words would i appreciate the upgrade?
