Even creating the boatable USB is already too complicated for 80-90% of users, but considering that we are on lemmy, most people here should be able to do it.

Choosing a beginnen friendly distribution means reading and comparing distros for hours if you are a complete newby. Just googling "easy Linux distro" or something like this will net you 15 different results.

Switching itself is easy if you define it as booting up Linux, but then what? You need drivers for all your hardware, a replacement for the MS office suit, alternatives for lots of programms, to relearn even the most basic commands and shortcuts and you have to manually transfer a lot of savefiles.

And that is ignoring the general pain that setting up your pc again is, especially if you have slow Internet.
