This comment is good, but it's very much the "scared of change" comment. It recommends the smallest amount of change possible, which might be good for some people but just diving in will probably be a better introduction.

You don't learn how to swim by sitting in a bath tub. You have to get into the water. Maybe wear some safety gear (dual boot or other options), but if you're reasonably confident and/or competent you'll be fine getting into Linux as long as you're using one of the major distros.

I assume almost everyone who has made it to Lemmy is competent enough with a computer to handle the transition to Linux. It really isn't all that hard if you know how to use a search engine.
