Q. Is this really as harmful as you think?
A. Go to your parents house, your grandparents house etc and look at their Windows PC, look at the installed software in the past year, and try to use the device. Run some antivirus scans. There’s no way this implementation doesn’t end in tears — there’s a reason there’s a trillion dollar security industry, and that most problems revolve around malware and endpoints.
I’m really hoping valve does a public steamdeck OS release. I’d like to replace windows on my PC with Linux and have windows as a backup, but the Linux distro I’m the most familiar with is the steam deck’s distro, and that’s not available outside of steam decks yet.
SteamOS is arch based and uses KDE Plasma as the default DE, so you could probably run Endeavour OS and be pretty darn close
