The code name of the first Steam Box, before it was released, was Piston, which fits the theme pretty well. e.g. https://www.polygon.com/2013/1/7/3849284/piston-valve-steam-box-xi3

Switching my phone screen to black and white actually does help, but the temptation to switch back is powerful.

I don't think it's most yet, but it's improving fast thanks to the Valve Steam Deck. Bazzite is probably the distro to look at for a machine that's primarily for gaming; it's based on the Steam Deck OS, but works on more machines. There are some high-profile games like Fortnite that won't run on it, but a lot of stuff will, especially if it doesn't rely on any fancy anti-cheat stuff.

I'm kind of reluctant to buy a headset with Google's new VR OS on it. Cardboard was kind of fun until they cancelled it. Daydream wasn't very good because they gave it a 2dof controller, but then they finally added 6dof head tracking--but then they cancelled the project before the headset actually came out (the one with 6dof tracking, I know the 3dof daydream headset exists, I have one. I think the 6dof one did come out [Lenovo Mirage] but the project was already dead at that point). So that was a bust. They also had project Tango for AR, but then they cancelled that right around the time an actually decent phone with support for it came out. And there was the VR180 video format, where they teamed up a bunch of hardware manufacturers, but then most of those never actually made it to market either and they dropped all the language about the project from their website. They also had that lightfield video project that allowed you to move around within a small volume, but they cancelled that project too.

Google's attention span with VR projects just seems to average about a year, and I don't want to shell out high-end headset money for something that might get bricked in an year.

Oh, cool! I didn't know about that. I might actually check it out once that's released.
