The folks at Gizmodo have obtained leaked pictures and specifications for an upcoming ThinkPad X300 notebook from Lenovo that is already being touted online as an "answer" to the new MacBook Air. Weighing in at 2.5lbs, the new Thinkpad would sport a 13.3 inch LED backlit screen, up to 4GB RAM, and a Merom-based 2.0GHz "Dual Core Hybrid LV" processor with a 12W thermal envelope.

On the connectivity front, the X300 easily trumps the MacBook Air thanks to a combination of 802.11n Wi-Fi, Gigabit Ethernet, Bluetooth, WiMAX, Wireless WAN (for Verizon, Cingular, Vodafone, and KDDI), and built-in GPS. Other features include an integrated ultra-thin DVD burner, webcam, fingerprint reader, three mini-PCIe slots, three USB ports, and will reportedly ship with a 1.8-inch 64GB solid state drive as standard - which could make the X300 start off as an extremely expensive notebook. So far, there's no word on pricing or availability and Lenovo has yet to confirm the ultra-portable.
