Yeah, I prefer a skinned Windows 10, which shouldn't be an issue since the XBox One is actually a skinned Windows 7. Otherwise you lose the huge existing PC gaming library and have another platform splitting up the userbase. Much easier to just have games made for Windows 10 work on SteamBox because its running the same OS, just a tweaked image where its skinned and remove everything you don't need and stop unnecessary services.It does because you're not suppose to know it runs Linux on a SteamBox. Just like you don't know the OS that runs on 360 or that PS4 runs a form of BSD. It's a dumb box meant for dumb dumbs. Valve doesn't expect you to get up and learn Linux to play games. You're not meant to look behind the curtain. Ignore the OS behind the curtain. You've been doing it this whole time with Xbox and PS.
Unless they removed Windows and used Linux instead. Then it wouldn't be at a loss.
