I want to use linux and will use it when two conditions are met:
-All my work software and the games I play the most all work on it (without requiring me to re-buy shit I already own to get a linux compatable version)
-Its user friendly enough that asking which version I should use as a beginner doesn't result in all the linux users immediately descending into the thread equivelent of a cartoon fight cloud with random limbs flailing around.

Edit: Some feedback on the feedback:
-Apparently some of the linux versions are super user friendly but advice about this is totally inconsistent, some of the advice doesn't even actually name a specific version or versions.
-"It all works fine you just need to install thing A through thing B and then use it to run thing C in order to run this one single program from windows" is not as encouraging as you think it is. The thought of potentially going through that for every piece of software is at least for me a big reason for not switching yet and I suspect for a lot of other people too.
-The reference page for what games work on linux is helpful though some things on it only work if you use the steam version which is the precise reason for my not wanting to re-buy things comment.

Edit: Additional question.
Is it mandatory to use the terminal for everything? Everytime I see people talk about linux or look stuff up about it the terminal seems to be everywhere. I'm somewhat familiar with the windows command line (which I assume is the terminals equivelent) but having to use that just to install software (as opposed to just running a .exe) seems really daunting.
