Here seriously looking for alternative to Win 11 for small family company becouse buying old computers with Win 10 Pro gives just few years. Best thing I found is invoicing app written in Java LOL. Need to call that company and ask do they support non Oracle Java :> But other then that, Linux is good, Emacs can generate simple pdf's to print, Perl scripts still able to sum few digits, even git via ssh works like NAS :) Just that mandated by law things are impossible. No monopoly at all...
