Despite a rocky launch and Chromecast availability, Google TV soldiers on. And, at $100, the Vizio Costar is the most economical of the bunch. After a number of software updates, including availability of a full-on Amazon Instant app, the Costar warrants a look. Also unique at this price point is Google TV‘s HDMI pass-thru functionality, allowing you to overlay the UI on top of another set-top or the HDTV itself – merging multiple sources onto a single television input. Further, the (bulky) QWERTY remote has an integrated IR blaster to potentially control those other aforementioned content sources. Due to a USPS/FedEx shipping debacle along with kind intervention by Vizio PR, we ultimately ended up with two units. Our pain is your gain and this brand spanking new Vizio Costar is up for grabs to Zatz Not Funny Facebook fans located in the US and you can enter using the embedded widget below. The giveaway ends at midnight tonight (EST), so act fast. Good luck!
