Elmo’s Boxi MP-350 seemingly does the impossible. It’s tiny and weighs just 1.1-pounds, yet can fill a 68-inch screen and move easily between rooms. Rather than a traditional lamp, the MP-350 uses a laser and puts a 1,280 by 720 image with 300 lumens on the screen. It has WiFi built-in as well as the ability to project from up to four sources at once. It sells for $659.
