Original-Syn if it's not what you wanted for an office?, then what exactly are you looking for, for an office?
Because for lay people, office personnel, etc. there's just noting better than an immutable system like what project Universal Blue has to offer.
Do you want a Linux system that can break? Like Ubuntu, Debian, Solus, Arch? Yes, they are not immutable and they DO break and HAVE broken on updates.
Or do you want a new technology like RPMOstree, OSTree, A/B, BTRFS with rollback etc. that can't break and if they do, you can rollback?
I would never install Solus or any other un-immutable system for a "regular user" that comes from Windoze. I would install an immutable, unbreakable system, for example like Bluefin (Yes, it IS unbreakable, by design) and the user doesn't even have to worry about updates or an update breaking his system because the images pushed are curated.
Can Solus guarantee this? NO!
Can Ubuntu guarantee this? NO!
Can Red Hat guarantee this? NO!
Can Bluefin, Bazzite, Aurora, EndlessOS, Fedora Silverblue, Fedora Kinoite, Ubuntu Core, Manjaro (with BTRFS rollback), OpenSUSE Micro OS guarantee this? YES, they can and is exactly what they do and offer a protection that no other "regular" monolithic single image filesystem can offer. There's no contest here. It's simply an advanced technology that is being implemented in the latest Linux trends and will be the future, no matter if some like it or not, it's here to stay and other distros will either follow or stay behind and go into oblivion. That's just how technology works and I will never go back to a non-immutable distro, unless I have to, like in my case with the Chrome book that I had to go and install Solus because it's the best "regular Linux" as far as resources on limited hardware. For anything else, there's just no contest. Project Universal Blue is just way way ahead of the croud.
