Warpia  projector connector

Getting PowerPoint to show up on an overhead projector or flat-screen TV is no big deal, assuming a pricey A/V tech is on hand to set it up. Now, however, the Warpia provides a wireless connection between a laptop and a projector or TV, making even the most tech-challenged presenters look like pros. Just plug the two adapters in, and the connection will work up to 30 feet away. Cost: $119.99, or $179.99 for Warpia with audio. (877) 704-0511; warpia.com
