Lenovo X300 lighter than the Air??

Lenovo will soon add another laptop to its Ultralight X300 Series. The specs are out, here it follows — a 13.3-inch LED backlit 1440X900 screen, an ultralight 2.5 pound form factor, and Intel Merom Santa Rosa Dual Core CPU (2.0 Ghz / 880 Mhz ), a 64 GB SSD, up to 4GB of DDR2 PC2-5300 memory, and 4 hours of battery life. Seems to be better than the MacBook Air atleast as far as specs are considered. Lenovo taking the competition to Apple.
