Hi all, long time lurker, first thread... Here's my situation. I'm a college student with a 17" mbp (it's a core 2 duo, couple years old). As a CS major, I love the huge screen for programming, it really comes in handy. I do however want something lighter that I can carry around when I won't be working for a long time, or if I'm biking or whatever. The air seems like the obvious choice. It seems that the refreshed airs will be out within a week or so with sandybridge and thunderbolt. TL; DR My question is, how suitable are the old airs for the programming, notetaking, etc that I would be using them for? I don't need it to be a speed demon but I don't want to be frustrated by slowdowns and pinwheels. Also, how much will the refurbished current gen airs cost once the new ones come out? THANKS!
