So I am starting college in a few weeks and I need to ditch this old Late 07 early 08 Macbook, my mom wants it so before the apple care runs out (was purchased and sent to me while I was overseas in a harsh climate) going to get the bezel and key surface replaced. I have several questions, I was inspired by another post here to consider the base level MBA + iMAC combo, my requirements: -Something small and mobile, I will be biking to school a lot (MBA) -I want something with good battery for notes (I have classes all day two days) (MBA) -Screen real-estate for studying (iMac) -I need something that can handle Aperture and other photo editing/managing software (iMac) -Some games would be nice, mostly minecraft (iMac?) Now the questions: Are there any of the upgrades I should consider? I pumped the Air's ram since I am not confident about after marketing the air. Applecare do you get it? I've never had a major mess up during the applecare plan periods with my hardware. i5 vs i7, is it worth it to spend a little more and jump the the more expensive 21.5' I am trying to be somewhat economical, but I need some stuff that will get my work done. Thanks for any responses.
