Lenovo's ThinkPad W700 isn't exactly thin or light, with its 17inch display, built-in graphics tablet, dual hard drives, and rated weight of 8.3 lbs. Maybe Lenovo thought that wasn't quite tricked-out enough, because it's about to launch a version of the same notebook with a secondary display for on-the-go dual-screen action. According to eWeek, the ThinkPad W700ds (the "ds" stands for "dual screen") will come out at the Consumer Electronics Show in early January. From the right of the already large 17inch 1920x1200 display, users will be able to pull out a secondary, 10.6inch LCD with a 768x1280 resolution. eWeek's photo gallery shows one possible application: in Adobe Photoshop, the ThinkPad displays the main image on the primary display and all the palettes on the secondary one. Surprisingly, eWeek says the secondary LCD only increases the W700ds' thickness by 10 mm over the regular W700. You'll have to pay an extra $500 for the privilege, though, which should bump up the price to around $3,000.
