Projectors go wireless

New AV gear reduces presentation clutter - but adds new glitches.

As head of Boston Flight Sciences, an aerospace engineering firm, I often present at hotels and convention centers where everything depends on the projector I bring. In principle I like tech that simplifies my life, so I was pleased to review three new wireless LCD projectors.

The NEC NP3150 comes with an optional carrying case, but at 16 pounds it's unlikely to leave home base. The unit sports a well - designed chassis and ports for every conceivable cable end. Startup and operation are both fiendishly complex, however, and to use it wirelessly, you need a separate 44-page manual.
