I know the buying guide on Macrumors says it's a good idea to buy, but i've heard/seen rumors that Apple will, very soon, have a huge overhaul of the Macbooks, with new aluminum and stainless steel cases, upgrades and the works. So, would it be worth it to wait until, say, late June or early August (I'll definitely need it by then to start college with) to buy a Macbook, or would it be prudent to go ahead and buy one now?
