You say you didn't pre-order a MacBook Air (unlike some bloggers I could name)? No problem! The Boy Genius Report says that Apple Stores already have them in the stock rooms (cleverly disguised as stacks of interoffice mail, no doubt), and they will be going on sale this Wednesday. The Apple Geniuses just need to get their bearings with the new laptops and all should be set.
Let us know in the comments if you spot a MacBook Air at your local Apple Store.
