The title pretty much says it all. How much time until these new MacBook (Pros) will end up in the refurb section? I'll be back in the US for December and since I'm usually a cheapskate, I get the lowest-end stuff. Until now, I was going to settle for a newer MacBook (white), which I have now (early 2006 model, refurb), but I think I'll go for the new aluminium ones. So, 6 months, a year? Longer?
