Summary:

- The Steam Link is a device that allows you to stream games from your PC to your TV, so you can play PC games on your TV without having to move your computer.
- The Steam Link is still useful because it lets you play your favorite PC games on a bigger screen, even if your computer is in another room.
- You do need to have your PC turned on and connected to the same network as the Steam Link for it to work, but this lets you enjoy PC gaming from the comfort of your couch.
