Appletell reviews the DoubleSight Smart USB Monitor DS-70U

The DoubleSight USB monitor is one of the many options available today in the world of USB displays. DoubleSight has 7 and 9 inch models, and you can even get a webcam to go along with the 9 inch model. The 9 inch also obviously benefits from a higher display, but both are about the size of an average netbook screen (if that’s something you’re familiar with). I tested out the DS-70U, the 7 inch model. The display powers itself and connects to your Mac (or PC) using two USB connections.
