This is a report from web browsers to major websites so it doesn’t apply much to the steam deck. I doubt most people are using theirs as an everyday desktop
When was the last time you tried? And Wine and other similar programs have come a long way. Especially what steamdeck/proton has done for gaming is insane.
I usually try Ubuntu Mate because I figure it's the most "normie" distro and should have good general hardware compatibility. I last tried it probably a year or two ago. It's been many years since I used Wine, but my lasting memory of it is that it's super clunky and buggy.
I ditched windows 12 years ago and never looked back. Its gotten easier every year and I rarely if ever have to tinker with anything. It just works. Ive had the same arch (btw) install the whole time just moving the image to new computers whenever I upgrade hardware.
I think I have replacements, equivalents, or Linux versions for most of my software, it's mainly the graphics drivers that suck with multiple displays. It constantly forgets the layout or leaves one of the displays inaccessible or just blank.
I also use DisplayLink for one of my monitors. I can't remember if that even worked at all.
If that could finally be fixed, it might push me to Linux.
There are a lot of cases that having different resolution can cause issues. I am glad you didn't have problem but this doesn't apply for everyone unfortunately
Love Linux but that's mostly steam deck pumping up numbers. Look at year over year desktop usage and it's not spiking even though it would be cool if it did.
I do like that tabs got added to file explorer and I almost always enjoy UI changes so I like the new desktop and menus. Control panel is always still there if you want the classic style settings.
