So I want to buy a MacBook Air, base 13" model for $1249 with my student discount for my first year of university. The reason why I am purchasing this is because at orientation I was told that the freshman coming into university don't do any heavy lifting with their computers. However, sophomore and above need a fast computer. So I plan on buying a MacBook Air 13" now, then when the new Pros come out in late winter/early spring 2012, I will sell the Air and buy the new, hopefully redesigned MacBook Pros. How much do you think I would be able to sell the Air if everything is in 100% condition if it is still the most recent model at the time?
