7 Gadgets to Save Your Next Presentation
Epson EX7220 Wireless WXGA 3LCD Projector, $650
There's one feature on this portable projector that can save your presentation from a common problem. A slider located near the lens can adjust keystone faster than you can say "investment dollars" to a group of venture capitalists. The projector weighs only about 5 pounds, has a bright 3000 lumens bulb, and runs at a crisp 1280 x 800 resolution.
