I didn't know that this existed yet. If you happen to own any games on steam you have to try it out once you get your Surface 3. I tried it today on my 13" macbook pro using my alienware alpha as the host computer. I was able to stream really graphically intensive games that my macbook wouldn't be able to handle. I am really looking forward to doing this on the Surface 3. For me, this pretty much eliminates any care about the Surface 3 not being able to play games since I can just use Steam Stream to play stuff if I want. *As soon as I get the Surface 3 on tuesday, I will post some videos of gaming on it using Steam Stream.
