Use the portable Joybee in the boardroom and family room.

A yawn-inducing Grand Rounds presentation wouldn’t be complete without the whir of a clunky 7-pound projector emitting blurry images of powerpoint slides onto a wall or whiteboard.

While the presentations themselves may never improve, the projector has gotten a serious upgrade.

At long last, there’s an affordable, truly portable projector that throws up a darned fine image — up to 80” (diagonal) in a darkened room, 40” in a room with just the shades pulled.

The Joybee GP1 from BenQ connects to a laptop and also sports slots for a USB flash drive and the iPod/iPhone (a dock is sold separately).  It’s powered by the company’s proprietary 3LED technology for clearer, brighter and more vivid images, which are even adjustable for wall colors. A 2W built-in speaker rounds out this 1.4-pound wonder.

Outside the hospital or conference room, think family fun. Thrill the kids by hooking up the Joybee to your iPhone with a movie downloaded or to a gaming console and projecting it somewhere unexpected — like poolside.

It’s portable entertainment that’s way more fun than Grand Rounds.  (BenQ, MSRP $499)
