Just introduced, $50, designed to compete with the google chromecast.

We have a ROKU 3, $100, which we really like. The stick is missing two features that we use on the 3. The stick is wifi only with no Ethernet jack and stick remote does not have the ear phone jack. The stick remote also does not have motion sensors for game playing.
For both the 3 and the stick the only output is HDMI, no separate optical digital audio. Anyway Netflix surround sound is Dolby Plus which is not supported by optical cable. So you will need either an A/V receiver or a TV that will decode Dolby Plus. Otherwise you will only get stereo.
