That number is going to go way up in 2025. I have a bunch of Windows 10 PCs that are perfectly capable that I manage that aren't going to Windows 11. I'm not alone.
I gave Linux another shot this past month. It was a lot better than I remembered, but still not good enough, basically in the reliability areas. I wish the experience was “it all just works” like so many have said.
I may not mind giving it another try when Windows Recall goes live.
I'd love to make the move, but there's a one-two punch of: I play Warzone with family. I think anti-cheat there is only going to get worse. Second? I already get caught with the fiddly bits of errors on Windows sometimes and spend too long searching for answers. Any time I see that on Linux it looks like I'd need years more of active learning new problem solving to reach my current level of comfort.
I'm at that "is it worth planting the apple tree now that I didn't plant 20 years ago?" thinking.
I just converted my other brother the other day. atomic distros are great when you are the family tech support guy. Made an ssh only user on all the family computers so I can remotely deal with most of their problems without having to actually touch it or remember their login details.
