DoubleSight Displays has introduced three new Smart USB monitors. They are available in 7 or 9 inch models, and are mostly identical in design, except that the DS-90UC model has a detachable webcam and the two 9-inch displays have 1,024 x 600 resolution, while the 7 inch display has 800 x 480.
The 9 inch model costs only $20 more than its smaller counterpart, $140 vs. $120, making the choice easy. The webcam-equipped version will cost you $160. A tiny monitor can come in pretty handy for things like Photoshop or email.
