Projectors go wireless

NEC NP3150

$4,999

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.
