Yes, Windows is far from perfect and has gotten considerably worse with Windows 11. I've been using computers my whole life and have also used many Linux distros over the years, and I've had a Steam Deck since its launch. And despite being someone who is quite good with computers, Linux has often been a real pain in the ass.
Windows, with all its flaws, is a much simpler and more polished experience than any Linux distro, even simple ones like SteamOS. Basically, Linux is like using a system that is always in alpha version, with problems that in many cases are specific to your distro, and with an elitist community that hates newbies.
It's going to be very funny when, led by the recommendations of "techtubers," many venture to install Linux and come face to face with a complex system, where one wrong command can break your system, where for small apps that in Windows you just download and run, you have to compile software and install dependencies using commands or find a compiled one that works with your specific distro... And then pray that all your plug-and-play devices are detected by your system... or you'll have to spend hours searching forums for solutions from 5 or 6 years ago that in many cases no longer work.
And then install any game outside of Steam and find that the videos don't work (Steam uses a hacky trick that involves recoding the videos) and so on...
