I am purchasing a MBA to replace my crappy laptop for school next year. I have two options.. 1) My friend is willing to sell me his Late 2010 MBA (high-end model) for $650. The laptop has 2.13 GHz Intel Core 2 Duo, 256GB SSD, and 4GB RAM. 2) I can purchase the new MBA for $1200 (upgraded to 8GB RAM with student discount). I am currently leaning towards buying my friends laptop.. do you guys think it will be too slow after being two years old? He has not used it much since he had a 17" MBP that he used most of the time.
