Little tiny Android based Mini TV interfaces that plug into the HDMI port of your TV, and connect to your WiFi. You can do just about anything on your TV, that you can do with your phone. You can also plug in external hard drives to watch movies or play music. Paired with a wireless keyboard/touch pad, it's a vicious little toy for under $100.
