4 New Projectors for Any Surface
Image quality was outstanding on this 3,000-lumen short-throw projector, which sits on a table or mounts to a wall right next to the projected image (the mounting kit costs $379). Its 2.5-ounce pen was the most accurate for making notes. You can also use it to highlight text and undo mistakes. As with the Dell, the pen also acts as a mouse, with left- and right-click buttons and a scroll function. One drawback: The projector's interactive software is not compatible with Macs. The projector bulb lasts about 4,000 hours; replacements cost $279.
