It appears that Valve have stopped making its Steam Link Hardware, and are moving to just using the Steam Link App on Android and iOS.
I have been a fan of the Steam Link since its launch, which is a funny story.. I per-ordered both a Steam Link and Steam Controller through EBGames (GameStop for Canada). I went to pick it up on the day of launch and found a huge line of people! I quickly noticed that everyone was getting copies of Fallout 4 that released the same day. When I got to the counter the guy asked “What system?”. I said “Steam Link, and Controller”.. He paused for a minute and then had to get someone to figure out what I was talking about.
It gives you an idea of the following the device had from the start. I have only ever known 1 other person that owned a Steam Link.
I don’t tend to use the device as my main gaming experience, but it’s really hand to keep on the TV in the family room if on the off chance I want to play something there with Trent or Erika. Its also been handy to play some videos or do anything from the desktop. You can close Big Picture mode and with a controller use the analog stick for mouse and triggers for mouse clicks. Its pretty slick once you get use to it.
So its a little bit of a bummer they are stopping production of the device. I think its more a cause of no one really giving it a chance and assumed it would be crap, than a sign of bad hardware.
I have had no issues playing Lego games or Tomb Raider, or anything like that on it (in Windows or Linux). I would advise against anything like Rocksmith or competitive gaming with it.
