I see these MFs on a daily basis

I'm certainly buying one of whatever they release.

A large scale migration would be wild. It would be like the Commodore 64 all over again - where one of the coolest things in gaming also happens to be the most functional personal PC of the year.

I guess it could happen.

Back in october I travelled for a lan party. I didnt bring my linux desktop with me, and just brought my steam deck and dock, and when I got there, borrowed a keyboard/mouse/monitor.

Then i swapped it to desktop mode, and the people I was with all commented on "Oh wow! it's just like a regular computer"

One of them has explicited said they were fed up with microsoft's BS and would swap their gaming PC over to steamOS once it's formally released for desktop (they were uninterested in Bazzite and wanted an official Valve release for their gaming PC).

I thought the holdup was the graphics drivers (Nvidia mostly) not the de. Normal desktop mode with KDE works fine on my steamdeck.

Fair point. But even so I think SteamOS has the most viable potential to achieve something like a 5-10% adoption rate that could get entities like nVidia to pay more attention.
- Lol can't disagree with you there, they just need to release it already!
It's pretty much just graphics cards at this point and games. Printer is weirdly enough work better on Linux then when I first started back in 2010. It used to be that everything was proprietary weirdness nowadays you just plug and play on Linux and then it's Windows where you have to mess with drivers. Personally I switched away from all in ones and just got a flatbed scanner so I never have to worry about needing that feature. I still need a good printer that isn't on the Israel BDS boycott and is cheap to operate on a per page basis. I feel like if printers weren't a scam more people would use them for more stuff again
- As you're a Linux user, I would assume that you've heard about brother laser printers. Why not one of them? Or a used version if they're on the boycott list? Aftermarket toner is cheap for them
  
  I used to have one and I was happy with it but I was foolish enough not to take it with me last time I moved. Is that still the consensus pick?
  
  Maybe 2 weeks ago accusations were flying that brother bricked printers using aftermarket ink after a firmware update.
  
  Evidence was scant, and brother insists they aren't doing that. So if you do get one, maybe don't update the firmware.

Will ValveOS be useful for anything besides playing games?

Games are pretty demanding, there will probably be widespread support just coincidentally. Also companies build software for where the market is, a big Linux population will command more development time for drivers etc.
If it is useful at only playing games I think it will be a popular option nonetheless.
- Sure, lots of people mainly use their computers for games, but I would think even they would demand at least a web browser and/or social media apps.
  
  SteamOS has a web browser.
  
  It boots by default into Steam Big Picture mode, which is the SteamOS/HTPC style "intended to be used with a controller" layout.
  
  In the power menu, it has a "switch to desktop" button that drops you to KDE. Firefox is pre-installed, and immediately available for use.
  
  But also, it's just an immutable OS with plenty of things installable via flatpak in KDE Discover. Which means Slack, Discord, Zoom, Chrome... all of the "desktop" things most people need are available.

Only a small fraction of people use Steam so I don't see that happening.

Steam apparently has about 130 million monthly active users and about 70 million daily active users. About half the planet has a computer at home. So, Steam users are somewhere between say 2% and 10% of the world's active PC users.

If someone is a daily active steam user, they spend a lot of time on the computer. If they have to make sure their drivers are up to date and their frame rate is high enough to support their games, they've probably developed a bit of knowledge about the system. My guess is that people who play Steam games tend to be the tech support people for their friends and family more often than not.

So, it's a small group, but it's an influential group. If enough of that group becomes comfortable with SteamOS, they may be comfortable setting it up (or a variant of it) for a friend or family member, even if that friend or family member only uses their computer to watch videos, check emails, etc. In a world where Windows was free and just worked, that might not happen. But, in this world Windows 10 is about to lose support, and Microsoft is suggesting that if your computer can't run Windows 11 you should just throw it away and upgrade. In that world, more people might end up switching to Linux.
- Why would you set up Steam OS for a family member. That is problematic in many ways.
  
  I could care less if Linux explodes in market share or not. It serves my needs fine and that's all that matters for me.
  
  If steamos just works you could just have the music. Steamos is also going to be the charging horse that lets everyone else in the door so they won't have to use it
  
  I haven't used SteamOS so I'm speculating. But, it's probably possible to boot to a desktop instead of to Steam. It's probably easy to install Firefox (or Chrome) and Thunderbird. I would expect that Valve has made the desktop experience easy to use.
  
  So, why install SteamOS for a family member? Because you have a desktop OS that's easy to use that a big, rich commercial company is spending a lot of R&D effort to make as good, easy and smooth an experience as possible. Even if the primary use case is playing Steam-based games, if you have a family member who just wants an easy-to-use OS that just runs their web browser, an email client, and a few other odds and ends, that might be the easiest way to do it.
  
  It's immutable (you can't break the core OS, there is no deleting system32). You can't install packages (like you would from AUR), but have access to flatpaks.
  
  Firefox is preinstalled, but anything from flathub is also available.
  
  So yes, it has all the things most people need from a desktop OS, and is harder to break, and is supported commercially.
  
  It has a desktop mode, I've never looked into whether you can boot to desktop by default. But I would imagine if they released a desktop friendly version, that would be an option.
  
  Yeah, so it sounds like a good choice for a relative who isn't a gamer but wants a hard-to-break simple OS that runs basic things like a web browser, email client, etc.
  
  It's probably too soon now, I just checked and it doesn't quite sound like it's very stable yet (as in, they're still tweaking it). But, maybe by the time Windows 10 is no longer supported it would be a good option.
Maybe. I just mean once(if) there becomes an OS that reliably runs Steam and the games on Steam, there will be a viable alternative to Windows for a significant population of users.
- I disagree
  
  Most people just want Windows
