Roku, the company behind a set-top box that connects any TV to the Internet, has launched the Roku Stick, a small $50 dongle that operates a lot like Google’s Chromecast, which sells for $15 less. The Roku Stick offers at least one advantage over Chromecast, giving users the ability to plug in a headphone jack into the Stick’s remote control, allowing for private listening.
