From a technical standpoint, yes, it is simple. From a user standopoint, it is complex af>>2114479>Is Linux pretty good? Also what would be a good distro?
Depends on your use cases. Debian and it's derivatives like Mint or Ubuntu are good starting points. Manjaro is too but it's based on Arch, which makes it sometimes tricky>I'm not very familiar with it, but I wouldn't be opposed to switching if I can get it to run Windows apps.
I'm gonna cut you /g/'s usual rant on proprietary software and free software, let's say some things simply do not exist on linux, but there are alternatives. e.g: photoshop and Krita.
Steam and some games are on Linux tho, which might make Linux more relevant for everyone>I'd contribute wallpapers or make OC, but I'm not really sure what to make.
it's ok, do as you want
