But if they really are going to be a healthy contributor to the whole community, then it makes sense for them to pick one and contribute to it. Who knows what's actually going to happen! I don't want to get my hopes up, though. Graphics support sucks in Linux for (presumably) some economic reason - maybe Valve entering the market is just a hedge against Windows locking down their software market and they don't really care about Linux or at least not about the wider community.
But Gaben has said some pretty promising things. Who knows. Very interesting and exciting, isn't it?
If Valve makes a complete custom environment for steam OS built around big picture will they really benefit more from using ubuntu versus debian, fedora or any other distro?
Does anyone _not_ expect Valve to throw that all away in favor of big picture mode? Unity, if it does ship in Steam OS by default, will be the under-the-hood interface.
I personally switched from Ubuntu back to Debian when I realized that I was dealing with Ubuntu-specific bugs more often than I was benefiting from Ubuntu-specific features.
But even if they are working with Ubuntu for some of the reasons you mentioned, that doesn't mean that they have to go with Mir. You could install Mir for any distribution. You could install Wayland on any distribution. You could just keep going with X because at least it's stable and people know about it.
