Lenovo announced their latest addition to the Thinkpad W700 - a second LCD display!
The primary LCD display is a 17" WUXGA supporting 1920x1200 while the secondary LCD display is a 10.6" WXGA supporting 768x1280. The secondary LCD display would unfold/swing to open next to the primary display providing an extended desktop.
Also in the W700, Lenovo's flagship and the ultimate mobile workstation, is a WACOM digitizer on the palm-rest, and color calibration.
The new model would be available in January 2009.
UPDATE: Here's a YouTube video of how the second screen is integrated into the unit
