A Taiwanese company wants business travelers to leave their laptops at home. Its new pocket-sized device plugs into a TV or projector and wirelessly downloads PowerPoint slides or streaming video from a smart phone, which acts as a remote control. The device comes with software that modifies the phone’s video output so that it has high enough resolution for a big screen. It can also work with computers, however, streaming high-definition videos to a TV.
Cost: Less than $200
