What OS are you using?

windows 10 at this moment

Mine is windows 10 ultimate!! ON laptop 11!

pc windows 10, laptop windows 11!

i updated windows 10 to windows 11 and i'm pretty satisfied so far

I had to get a new laptop so windows 11

Manjaro Linux with Win 11 in dual boot. Probably going to switch to Hackintosh soon tho for productivity reasons

MacOS Moneterey - honestly so glad I upgraded , alot faster than catalina

two devices one uses windows 10 and the other ubuntu

Abandoned Win10 out of hatred for Microsoft and have been happily running Mint 20.2 for about a year now, which I chose for reliability and long-lived community (easier troubleshooting).
Also use Ubuntu Server 20.04 and soon 22.04 for all servers

I am using a window 11 right now and ipad os 15 pretty nice
