http://store.steampowered.com/app/353380/Steam_Link/ I didn't know what this was... I guess you stream your computer games across the network to this lil box, and then you can use controllers to play games. It's 90% off. Looks like there's also an app on some Samsung Smart TVs, too. A quick look on youtube showed there were some other things you could stream, so I figured for $5 might be worth it.
I bought one at $15 with an unusual I unboxed and sold. Played with it once or twice. Haven't really had much time to mess around with it too much. Seems to work fine, but had issues with the games I was trying to play with the steam controller that I haven't been able to work around yet.
