Roku announced a new version of its Streaming Stick this week. “The newly enhanced $50 HDMI streaming dongle still outputs in HD and lacks the 4K capability of the company’s top-of-the-line Roku 4 streamer box,” notes Wired, “but faster processing speeds and updates to the Roku mobile app give the Streaming Stick a big boost.” The updated device is thinner, longer, and has transitioned from purple to black. Roku has improved performance, boot-up and navigation speeds. The dongle is powered by a quad-core processor the company claims will offer eight times the processing power of the last version. Available for preorder, it will start shipping in the next two weeks.
