This has just come in.. Rumors says that you could get your new macbook air by tuesday the 29th January. I can't confirm this rumor but it's comming from many different locations, so I wouldn't be shocked if it turns out to be true.
If you cruise up to the apple store, you can see that they will begin shipping the macbook air in 2 - 3 weeks. I don't know if they are behind schedule?
Apparantly the MBA:s arrived at all apple stores on Friday/Saturday.
My best bet is that the official release is either tuesday or wednesday.
