According to Gizmodo, details of ThinkPad X300 have been leaked:
“It appears that Lenovo have themselves a new ultralight X300 series Thinkpad—and outside of the price and release date, we have all of the specs that you need to know. At a glance, some of the major features include: 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. Hit the gallery for the full details.” – Gizmodo
This is some competition from Lenovo for Apple’s latest offering MacBook Air (world’s thinnest laptop), and a new ray of hope for ThinkPad/Windows fans. It may not be as thin as Air (unconfirmed) but has a better screen resolution (1440×900 vs 1280×800) and is half a pound lighter.
Update: Also see a specwise comparison of MacBook Air with other laptops in the ultra portable category (Dell XPS M1330, Toshiba Protege R500, Fujitsu Lifebook S2210 and Sony Vaio TZ150N).
