I am looking to get a new MBP to supplement my ipad, but cant decide whether i should go the refurb route. The only thing i do on my laptop is write papers, make some powerpoints, download music, and sometimes rip dvds. Would i notice the difference between 2 & 4 gbs of ram? and would i notice the difference between the 2.0 ghz processor and any higher processor? Thanks for any help. here is the refurb i am thinking of getting. http://store.apple.com/us-hed/product/FB466LL/A?mco=MTA4MzIyODg
