Lenovo is lunching first Macbook Air Killer from the PC side. Thinkpad X300 has 1.13kg of weight and it is 18.6mm thin.

Spec:

13.3 inch LED WXGA display (1440×900)

RAM up to 4GB

Gigabit Ethernet, IEEE802.11n draft, Bluetooth, WIRELESS USB, WIRELESS WAN

64GB of SSD

DVD Multi-drive

3 of USB2.0, ExpressCard slot/34

Ultra Nav (TrackPoint+touchpad)

Stereo Speaker

As I just wrote, X300 has almost everything in it which Macbook Air does not. If this Thinkpad runs Mac OS X, I definitely get this rather than Macbook Air.
