Months after bringing to the world an updated lineup of iMacs, Mac Pro workstations, and Macbooks barring the Macbook Air, Apple has finally given its due, with a new updated Macbook Air. Apple's ultra-thin, and ultra-light notebook is now available in two sizes, 13-inch and 11-inch. Internally, there are no radical changes. It still uses a Core 2 Duo, clocked at 1.40 or 1.60 GHz for the 11-inch and 1.80 GHz or 2.13 GHz for the 13-inch version with 3 MB (11-inch) or 6 MB (13-inch) of L2 cache , 2 GB of DDR3 memory (with the option to choose 4 GB), and NVIDIA GeForce 320M integrated graphics. Unlike with the older generation, the new Macbook Air uses SSDs on all available variants, it's hardwired on its motherboard (apparently to minimize space), and comes in capacities of 64~128 GB (11-inch) or 128~256 GB (13-inch).

It is over the hood that most changes are made. The unit is now thinner at 0.11-0.68 inch (0.3-1.7 cm), lighter at 1.06 kg for the 11-inch and 1.32 kg for the 13-inch. Apple claims to have learned a lot from iPad's design. It's given the new Macbook Air a larger glass trackpad that uses high-precision multi-touch surface used in Apple's touch products, which enhance the user-interface beyond just doing the work of a pointing device. The screen used has high pixel density, with 1440 x 900 pixels for the 13-inch and 1366 x 768 pixels for the 11-inch model. A high-resolution Facetime web-camera is fitted. The Macbook Air provides all the software capabilities of any other Mac, the Mac OS X Snow Leopard OS and iLife are bundled. Battery life has also gone up, 5 hours for the 11-inch and 7 hours for the 13-inch. Prices start at US $999 for the 11-inch model and $1,299 for the 13-inch one, and go up depending on the optional components chosen.
