The Steam Deck and it's desktop mode are why I decided to try jumping head first into a single boot of Bazzite on my main computer, it's basically like using a Steam deck, just across four monitors, it even has HDR support built in. A year in and I haven't looked back.
This is the exact kind of user interaction I'm looking for. I've wanted to switch to Linux but need something stable I can use for my Steam library, and web browsing.
Garuda Dragonized I really like. It's set up for gaming out of the box, with a utility to help you add anything else you may need for gaming. It comes with a "gamer" aesthetic that I'm really not a fan of but it's easy to modify. It's Arch based, which may sound scary from what you've heard, but it's really not bad. It comes with everything you need (which is where the trouble with Arch is), and Arch is one of the best supported distros, with the Arch wiki and AUR.
I've been single boot on Fedora for a little over a year. The biggest issue for gaming that I've seen are because of anti-cheats that don't support Linux.
Yup, but to add on to what the other guy said you will have to find alternatives to some programs like adobe products, microsoft products, and some others.
Just install Linux? SteamOS is just a Linux distribution based on Arch. My current distro is Garuda, which is also Arch based and has a gaming focused version with everything you need for gaming pre-installed.
How is CS2 working on it? I know I could just try to get it running myself on a spare pc, but I find that as I get older I dislike fiddling with things like this more and more. And while I'm fine with just playing games made to work properly on Linux, CS2 and it's predecessors is something me and my real life friends have been playing for nearly two decades. It's a way to keep in touch as everyone has kids and can't come to the pub during the weekend.
SteamOS will most likely be deployed on other handheld PCs, not desktop PCs. The handheld PCs that came out in response to the deck's release (or before) usually run Windows.
Android is not bad because Android itself is bad (well... it kinda is but let's just assume it isn't), but because the phone manufacturers lock down their phones' hardware. They do this to force you into their ecosystem. With SteamOS, you already have an ecosystem, which is Steam. There is (at least for now) a clear distinction between Hardware manufacturer and software provider.
For now at least Androidization is nothing you should worry about. Maybe in 10, 20 years. edit: and even then it's never going to be as bad as with the smartphones
