Well, about 4 or 5 months ago I returned my 13" for some drive issues and since I've just been using the same old PowerBook G4 as I had for so many years before it. Now, it's really starting to wear thin (or rather, should I say, I want Team Fortress 2 NAOOW!!!) and I've been thinking about replacing it AGAIN, this time though, I'm looking into the MacBook Air. Now, I never use CD's or DVD's anymore, and the portability just seems wonderful to me, even better than my PowerBook. However, looking at the buyers guide, it appears that it will be updated again soon. So I ask you, should I buy now, or wait for a couple weeks. If the next update isn't going to be huge, I don't really care about it. Another thing to ask is whether or not I should go refurbished. What are the key differences in the refurb units? Do they look used? Or are they outfitted with nice new body parts to make them look new? Note: I get student discount too so I'd be paying about 100 USD less than most people would be. I also have a Cinema Display and mouse, and if I need it, an external optical drive, so none of those are really going to be factored into the purchase, just the high-end MBA.
