I think a lot of the excitement for SteamOS on other devices comes from two things:

1. People not knowing what Bazzite is, or like yourself, not knowing what it does differently.
2. The fact that Valve’s support for other devices means Linux growing larger again, like the Steam Deck has done originally.

Bazzite is basically like if you handed your Steam Deck to someone that was really knowledgeable with all the time in the world to tinker, and they added all of the third-party quirks and features that Valve would never ship themselves for you. Things like:

• Decky Loader, which is a plugin manager that lets you add all sorts of stuff to gamemode easily. Stuff like a plugin that’ll notify you when any games on Epic, GOG, Steam of itch become free, one that makes airpods work seamlessly, ones to let you run custom themes, animations and sounds, etc.
• Handheld Daemon (HHD) which lets you do things like change whether the controller is emulating an Xbox, PlayStation or Nintendo controller.
• Lutris, which lets you install games from other stores, or from installer files, and add them easily to Steam for gamemode.
• OOTB tools to add other versions of Proton like GloriousEggroll.
• Scripts to set up all kinds of other things, like EmuDeck, Waydroid, SSH, Sunshine/Moonlight and others.

The only caveat I can think of really is that you’re relying on a small team that supports it, rather than an industry heavyweight like Valve. However, due to the open nature of Linux, all the tools that they’ve made for SteamOS are used here as well, there’s just a bunch they’ve layered on top to enhance and modify the experience.
