Video: Lenovo ThinkPad W700ds has slide-out dual screen

The Lenovo ThinkPad W700ds is built on the standard 17″ ThinkPad W700, but has a slide-out 10.6″ display. Lenovo designed this desktop replacement for graphics professionals and CAD designers that need dual screens and a portable (although hefty) computer.

The W700ds is certainly a powerful machine with interesting features, such as the built-in digitizer and color calibration, but I’m not sure its key feature, the slide-out display, really adds to the mix. The point of dual monitors is to expand desktop real-estate. Why not just ad a second LCD monitor to the W700ds instead of using the pull out display?

Perhaps I just don’t see the usefulness of an extra few inches of screen space because I’m not the W700ds’ intended user. If there are any graphics professionals or CAD designers out there, I’d love to get your impression of Lenovo’s slide-out display.
