You could, but what makes Steam Deck special is that it’s SteamOS is built specifically for that hardware, enabling functions you wouldn’t normally see in gaming PC hardware.
At least one of the main features is seamless suspend/resume. Not sure what the state of that is on Windows but I’ve seen a lot of people mention that SD feature specifically.
There’s also the global framerate limiter. Pretty sure that’s impossible to do on Windows.
Small nitpick. I’m not sure why you don’t like the idea of the vendor having stuff installed on hardware they make, to ensure it functions optimally. Like, on a primary compute device, sure, be picky about the OS. But this is a game platform. Nobody gives a shit that Nintendo makes their own OS for their hardware, why does anyone care how the Steam Deck does it’s thing?
