[CES 2010] If you’ve been trying to get an additional display for your laptop, but are always on the road, you’ll probably be delighted with the Cinq, by Sideline. This device can be attached to your laptop via USB (for both data and power), giving you a 10.1-inch, 1024 x 600 secondary display, and a SD card reader. It works with both Windows and Mac, and weighs in at 15.6 ounces. The device will be going for $249 in Q3, but if you want to save a few bucks, you can always pre-order it now from Sideline’s site, at a discounted price of $199.
