I'm graduating from high school on June 22nd, and I'm going to be taking summer courses at the college I'm attending on June 21st (lol, I know it's backwards, since I'll be going to college BEFORE I graduate high school). I'm desperately in need of a new laptop, and I really want a Mac. I was planning on buying one when I turn 18 (which is right before graduation) through Best Buy (with the best buy card, which I will be applying for). My question is, if the macbooks were to see an update/refresh in WWDC, how long will it take for the updated versions to hit retail stores?
