At the keynote yesterday Apple announced the world’s thinnest notebook. At it’s thickest point the notebook is 0.76 inches thick, amazing. The display on the notebook is 13.3″ (the same size as the MacBook) and uses LED backlighting for energy saving and more vibrant colors.

The new notebook weighs in at a little over 3 lbs. and has a full sized keyboard that is backlight similarly to how the MacBook Pros keyboard is. The notebook also has a very generous trackpad with multi-touch gestures (check out the video guided tour here for more on that). Above the display there is an iSight camera.

The MacBook Air has a nice little drop down set of ports on the right side that include 1 USB port (not enough in my opinion), headphone jack, and a Micro-DVI port (support for displays up to about 23″).

The hard drive in the MacBook Air is pretty interesting, to slim the notebook down to it’s small size Apple used 1.8″ hard drives instead of traditional 2.5″ notebook drives. The notebook comes with an 80GB 4200RPM hard drive standard with the option of a 64GB SSD.

The whole thing is powered by a 1.6GHz or 1.8GHz Core 2 Duo and 2GB of memory (not upgradable). Built in 802.11n and Bluetooth 2.1+EDR. Apple is claiming the notebook will get about 5 hours of battery life although my guess would be closer to 4 hours.

One thing missing from the notebook is an optical drive, Apple offers an external SuperDrive for $99 but another option is the ability to “borrow” another computers optical drive with a feature called “Remote Disc.”

The notebook will ship in 2 weeks and pricing starts at $1,799. Oh, and here is the ad for the MacBook Air:
