3M Has A New Twist On A Portable TV

Back in the day when over-the-air TV ruled, there were quite a few portable TV sets - ones you could take to a picnic or a tailgate party. Now 3M has come up with a new take on a portable TV - it's basically a wireless Roku stick and a DLP video projector in a small one-pound unit. So you get a small device, a large display capability and many channels for around $300.
