Upstream images vs bazzite: https://github.com/ublue-os/countme/blob/main/growth_upstream_with_bazzite.svg
My prediction: bazzite may have more installs than Fedora KDE by the end of the year.
I'm a Linux user since the age of Slackware diskette installs.
I tried Bazzite, or Aurora, rather, and found that it wasn't for me. Having to spin up distro boxes or VMs to do things that are pacman -Syu some-random-app in my current distro, is just not for me.
I lived in ultrastable Debianland for years, and recently tried Script Kiddie Arch (CachyOS). I have my at-least-for-now forever home.
I have a fairly bleeding edge distro that is slick, fast, polished, friendly, and If something goes boom, I have snapper and pika backing up, so in a few minutes all is back to normal, so the main selling point of atomic/immutable distro is kind of irrelevant to me, and I don't have to live in a system where the important decisions are made for me.
I have an old iMac for that.
CachyOS is friendlier and less problematic than W11, and if you need help, it's wiki + Arch's legendary wiki + community is way more useful than your average Windows "run DISM" bullshit.
