The latest innovation from Roku CEO Anthony Wood and his squad? After reducing the size of its players to a mere hockey puck, it has now managed to fit all the necessary hardware into this tiny dongle, that plugs into the HDMI port of MHL-compatible HDTVs. It allows HDTV manufacturers to build TVs that function as dumb displays without it, but become smart TVs featuring the Roku experience we've become accustomed to just that easily. The plan is to release the stick in the second half of the year, and Best Buy's Insignia line is the first scheduled to take advantage. Check after the break for the press release and one more pic of it installed in an HDTV.
