Review: 3M MP220 Pico Projector

Weighing nearly 15 ounces, the brick-shaped 3M MP220 is bulky for a pico projector—in fact, its more than twice as heavy as many competitors. And at $446 on Amazon (as of October 29), its pricey, too. But it also boasts the highest native resolution of the four projectors we looked at in our latest roundup—1024 by 600 pixels—and it can accept video sources with resolution of up to 1440 by 900. This means you'll be less likely to have to reduce the screen display of a laptop to use it. In fact, you might not need to connect it to a laptop at all: This projectors built-in Android software and 1GB of on-board memory (expandable via a MicroSD card slot) allow it to store and render documents and media files all on its own. It's a self-contained presentation system. Charging the MP220s lithium-polymer battery takes several hours; 3M says it will run for 2 hours on a single charge. When you turn it on (using a button on the right edge), the Android-based interface fires up after a few moments; you then navigate using a tiny touchpad flanked by the standard Android hardware buttons (home, menu, and return) and a search button on the top side of the projector.
