I understand where you're coming from. I myself prefer using a terminal for most things, and use arch (btw) for the PC I game on. I understand that learning Linux is the best move for folks, but I don't see that being an option, at least initially, for people on the fence.
I know that, from a Linux user's perspective, it is the wrong move, but I have plenty of friends that want a "no terminal, gaming ready" distro before they make the move. I see it more as a first step, removing the barrier for making the switch to Linux. Once they are already there, it's much easier to convince themselves to learn Linux a bit deeper if needed over time.
I don't know, maybe I'm just naive and hopeful, but there are a good number of my friends that I think will make the switch to Linux that wouldn't have without SteamOS.
I hold a firm belief he's trying to temporarily crash the market, so 47 and all his friends can "buy the dip", and then he's going to back out of his terrifs, the market will go back up (most likely not all the way up) and they'll now have a bunch of stock they got on the cheap
