Honestly if you go with one of the more popular Linux distro it's not difficult to set up or use at all, and I've used Mac and Windows for most of my life.

Like someone suggested maybe try a Linux distro through a live environment booted from a USB or use a VMare sort of thing to play around with it and see if it makes sense.

I dual boot windows and Linux, but I'm only ever on windows for gaming. I do everything else on Linux
