This landing page (and the associated support pages) weirdly never mention what they include in "your favorite stores". This seems like crucial information, and was certainly the first thing I wanted to know. Why not mention it? First I thought they might not support Steam and be ashamed of it, but the comments here make clear that they do. Then there are comments here talking about 4K, but Nvidia only seems to mention 720p and 1080p. Sure, most users' network connection probably isn't good enough, but why not tell us? It could certainly be a selling point for connecting this to a 4K television.
