Lenovo’s much-vaunted ThinkPad X300 grabbed its fair share of attention earlier this year due in no small part to its widely-publicized rivalry with the MacBook Air. Now that a few months have passed since the introduction of this 13.3-inch machine comes news of its smaller yet powerful brother, the Centrino 2-based X200, courtesy of some presentation slides leaked to Engadget.

The X200 will run on Intel’s latest low-power Core 2 Duos at speeds up to 2.4GHz, featuring DDR3 memory, a choice of solid-state drives with capacities of up to 64GB, an optional nine-cell battery pack good for 9.6 hours of use, a DisplayPort connection and options for 3G data, GPS, ultra-wideband, and WiMAX.

Weighing in at just 2.93 pounds this 12-inch system certainly packs a punch for its size, though you can probably expect to pay a hefty price for it. Three more conventional notebook lines are also receiving the update to Centrino 2, including the X200, SL, T, and R series notebooks. You can check out the full details at Engadget.
