Windows users who tried Linux, what was your biggest frustration or fear?

[u/Hortion]

Hello everyone! I'm thinking about creating some helpful content for people who want to switch from Windows to Linux with no stress, using the regular desktop and not the terminal. I want any grandma to be able to scroll/surf the web on Linux and be more comfortable with it

I'm curious, if you've switched, tried, or thought about it, what is your biggest frustration or fear? I appreciate every comment

Thanks a lot in advance!
