If you're unfamiliar with the Google Chromecast, do yourself a favor and buy it. I managed to hunt one down a few weeks ago. $35 for a Netflix and YouTube natively streaming device that plugs into an HDMI slot.
There are some hiccups: 1. Buffering issues occasionally 2. You must have a PC or Apple OS 10.7 to set it up currently. 3. The quality isn't that great considering the 25mbps I get from Comcast. 4. Did not want to work with the Comcast router (thankfully, I own an Airport and created a new network). 5. Netflix and YouTube are the only native streaming services (you can "cast" a tab from your Chrome browser, but the quality depends on your computer's abilities for any other feeds).
Here's why it's perfect for me: I have my nice electronics in the living room, but I had this 20" tv in my room with nothing getting to it. Comcast recently turned off the analog signal sent along with the digital and I don't want to rent another box for $10/mo. I already have netflix and an iPhone (also known as a Chromecast remote now). Look, I always lose remotes, but my phone is glued to me day and night. This thing is still in beta and for $35, I'm willing to sacrifice a little quality on my second tv. It's only going to get better and for the low cost involved, I'd recommend it to anyone with an extra HMDI port on an underutilized tv.
