Epson has expanded its VS series of small business-level budget projectors, with the VS210, the VS310 and the VS315W, the only one of the three offering HD resolution and a widescreen ration. All three identical-looking models weigh in at 5.1 pounds each, making them lightweight and travel-friendly, and deliver 2,600 lumens of light output. In addition, all three can use USB connections from Mac or Windows computers to carry audio and video rather than DVI or HDMI.
