There's got to be an easier -- and lighter -- way.

Welcome to the era of the microprojector. Rather than squeezing a five-pound projector into an already overburdened bag, imagine slipping something the size of a cell phone into one of the bag's pouches. Better yet, how about your jacket pocket? Weighing less than a pound -- often much less -- these pocket projectors can rewrite the rules of business travel.

"These projectors will be a relief to anyone who's lugged a projector on a business trip," says , senior analyst at Insight Media. "It takes one of the heaviest and largest items that businesspeople use and makes it one of the smallest and lightest."

Brennesholtz forecasts sales of at least 30 million tiny projectors by 2012, up from essentially zero this year. "This market is just getting started," he adds.

Unlike typical business projectors, pocket projectors are also aimed at consumers -- for showing a movie at a child's birthday party, watching the Super Bowl or having a video game showdown, for instance. All that's needed is a white wall or an old bed sheet tacked to the wall.
