The hard truth is that as much as you think yourself as a "proper" gamer, this segment always has, always will, _not_ be the proper target segment. Don't forget that mobile gaming has more revenue than everything else… combined. They have a play on this, and as much expansive as it looks, it's mostly due to the hardware inflation, and compared to alternatives, it won't look bad at all. For the segments that matters.
I don't see a market of people who want to pay Valve $1,050 to play Steam games on a custom Linux machine with old hardware that won't support big name games that have kernel anti-cheat on them.
I really don't see the vision Valve is looking for here.
