Today Apple announced it's release of the MacBook Air.  MacBook Air is nearly as thin as your index finger. Practically every detail that could be streamlined has been. Yet it still has a 13.3-inch widescreen LED display, full-size keyboard, and large multi-touch trackpad. It’s incomparably portable without the usual ultraportable screen and keyboard compromises.

Design
MacBook Air is a full-size notebook encased in the 0.16 to 0.76 inch of sleek, sturdy anodized aluminum. Weighing in at just 3.0 pounds, you won't mind taking it with you everywhere you go.

Apple did not skimp on the keyboard to reduce the size of the new MacBook.  The MacBook Air sports a full-size backlit keyboard and oversize multi-touch trackpad. 

Built for the wireless world
Apple says that they designed and engineered the MacBook Air to take full advantage of the wireless world. A world in which 802.11n Wi-Fi is now so fast and so available, people are truly living untethered — buying and renting movies online, downloading software, and sharing and storing files on the web.

Some of this I agree with but I wonder how functional this will be for the average user.  I for one do not download movies from iTunes.  Perhaps I'm living in the stone ages but I still rent DVD's and don't find it inconvenient  to simply insert them into my optical drive. 

There is a portable optical drive but who wants to tote that around.  I remember many years ago I had a PC with a portable drive.  I hated it then, I think I would hate it now. 

You can watch the full video of the new MacBook Air on Apple's website and decide for yourself.
