Sorry my implied meaning didn’t come across. It’s not better for users, it’s better for Valve as they are not taking on responsibility for maintaining other devices.

It would be nice if Valve did that, but I don’t see that happening. They have only done this much because Microsoft wanted to pull an Apple by not allow non-MS markets on Windows. At least with Valve being privately owned they are content to just keep feeding the goose laying the golden eggs.
