If you want an easy way to enjoy playing your Steam library on your big-screen from the comfort of your couch, the Steam Link is the perfect device for you/
The Steam Link is a small streaming box that you hook up to your TV and connect it to your home network. It will then stream all of the content from Steam running on your computer, allowing you to play remotely. While it pairs nicely with the Steam Controller, users have also reported being able to use their Xbox One controllers seamlessly with the box.
For some reason, Valve is currently offering the Steam Link for the beyond bargain bin price of just $2.50 (US). This also covers the shipping. This deal appears to only be offer for shoppers in the USA, so keep that in mind.
