I’ve gone all-in at this point, at least as much as I can. My work machine daily driver has been on OpenMandriva Rolling the longest. I switched in April of this year. Since then, I’ve installed two aarch64 servers running on Libre Computer machines: a LePotato and a Renegade. The LePotato is a Syncthing server I had to rebuild because it corrupted its microSD, so I figured, why not install OM on it? The Renegade runs NextCloud for my family.
This past summer, my wife ran out of space on her laptop, so I bought her a new 2TB NVME, installed it, and installed OpenMandriva on it. Now that the UM has happened, she’s back on her beloved Thunderbird email, which she’s used since the early 2000s. The GMail interface was really hard for her to take.
Also this summer, I installed OpenMandriva on an old laptop for my 11-year-old son, so he could start learning to type and learning how to use a computer. He’s also enjoying Xonotic. 
Finally, on my personal daily driver, I installed Cooker last month because I was running into problems with putting the laptop to sleep on Endeavour OS. That issue, unfortunately, seems to be a kernel issue, so it hasn’t gone away, but I am glad to be on OpenMandriva almost completely consistently across my and my family’s machines.
I have three other machines OpenMandriva has not yet assimilated. One is the main backup/file/Syncthing server, also running on a Libre Computer Renegade with ARMbian (its default distro). I don’t want to rebuild that box until I have to. Another is our “jukebox” machine that’s just an old laptop hooked to some nice speakers for playing music and showing family pictures. That one’s still on Manjaro. It’s working, so I’m in no rush to re-do it, but it is irritating, because it’s really just a utility machine, and it wants updates too frequently. And finally, when my daughter graduated from high school in 2023, she got a Thinkpad. At the time I was an Arch guy, so she got Manjaro (which is what was on my wife’s machine pre-OM). She doesn’t want me to touch her computer, so I’m guessing she won’t get OpenMandriva until that thing dies.
For me, OM has become my default go-to Linux, and it’s only a matter of time till it’s installed on everything.
