Windows refugee here. I installed Debian 13 with KDE Plasma on my main machine four months ago and I am still ironing out issues. Eg CUPS was asking me to login all the time and didn’t accept my credentials. After some days researching I discovered I had to log in as root. Then, I discovered I didn’t have root credentials for some reason. I had to create them and then add my local user to a group! Just to be able to use my home printer.
Or suddenly my clock was 62 minutes off. I discovered the NTP service was never set up properly and I had to install chrony.
I don’t see how I could have avoided using the terminal. These are only a couple of examples. No deal-breakers and on this occasion I had the time and determination to resolve them. I could have easily given up.
I thought it was Autonomy. You installed a program, instructed puppies agents, logged out, and while you were offline the puppies searched through several engines. Next time you logged in the findings waited for you. That was the time of 56k modems and metered connections.
