Story of a penguin fledgling, one of my end users whom I migrated from Win 7 to Linux Mint. She had been on Windows since Win 98 and still uses Windows at work.

Three months before. Me, Linux might not be as good, but Win 10 is even worse. User, mh.
Migration. User, looks different, but not bad.
One month later. User, it's nice, I like it.
Three months later. User, why does Windows reboot doing lengthy stuff?
Six months later. User, I hate Windows. Why is everyone using this crap?
One year later. Malware issues at work. User to IT staff, that wouldn't have happened with Linux. Me, that's the spirit!

Worst and only experience is the reason I moved away from programming...
25 years ago I was hired to copy a phone book list to a access database.
Access back then would create lots of garbage, so I would add 3 to 5 entries before access crashed (shitty p133 laptop with 32mb ram running windows 98.
So I made a visual basic program to add data and work around the problem.
I offered said program to the guy really cheap and would still make it better.
Did also a admin module since he had hired dozens of people and I knew he would have problems peasing the databases together.
And... Dude cancels the deal.
I get a job, 2 weeks later he calls me... Ohhh I don't know how to get all the databases together...
Me: I'm working now, the program I did solved said problem. I trew the code away. Deal with it.

Years later the supposed 'cancer' that is linux: a fully featured, and more and more polished FREE operating system running Microsoft development tools, a rich GUI which does away with the crappy windows 98 taskbar, multiple virtual desktops, and steam !

My first computer was an old Pentium 2 running windows 98 with no internet and just a CD Rom and Floppy Drive. Got it for my 7th Birthday I think and immediately wanted to make it do my biding.

Didn't work out. Had no clue what the words on screen meant and batch scripts looked like sorcery to me.
Hell even the options menu in German was a cryptic puzzle to me.

Got a little better in the meantime.
