When it comes to Apple, nothing is ever set in stone until Steve says so. With that said, quite a bit of credibility has been lent to the idea of a new ultraportable from Apple, with the possible moniker of “Macbook Air” or perhaps the “Airbook”. Interesting speculations include the possibility of integrated WiMAX technology from Intel, wireless charging capabilities, the lack of an optical drive and the inclusion of a solid state drive.

Why, you ask? A search for the term “macbookair” on the search engine DogPile reveals a yet to be run ad from Apple for the Macbook Air that leads to the Apple online store. It also looks like Apple is the owner of the macbookair.tld domain set.

9to5mac reader Jon Cotton discovered someone using a computer titled “MacbookAir” using the Adium program BEFORE the “something in the air” banner was unveiled.

Even Apple.com is getting in on the hype with a tantalizing “Something in the air” banner across their home page. The only sure thing is that Tuesday will bring us something interesting.
