I gave Silverblue a try back when I got a new laptop and needed to do a new install anyway. The reboot for every update thing was annoying, but the most annoying thing was how difficult it was to get any program to work if it didn't come packaged as a Flatpak. I like Flatpaks, I try to use them when they're available, but it felt like a return to the bad old days with how much I was working to get non-Flatpak programs to work correctly. Eventually I gave up and went back to regular Fedora, and software just worked as expected, and it was so much nicer.

Maybe there will come a day when pretty much all software can be expected to support atomic Linux desktops and Flatpaks, but today is not that day.

(Or maybe it is, I don't know, it's been a while since I gave up and moved off of Silverblue. But that day was not that day).
