It all comes down to the time you are willing to dedicate in learning something new.

For most of the stuff that runs on windows and mac there are alternatives on linux, some equal, some worse, some better. I have been mostly a linux users for years. I still have one laptop with a dual boot on windows...for only one use case: music production. Not because there are no music production software available, not because they aren't good, quite the contrary there are fairly decent tools both opensource and proprietary, but because I don't know them well. I only do music as a hobby in my free time and so far I have been too lazy, or more interested in producing music than learning a new workflow. I admit it is mostly about laziness and time to dedicate to something new. I intend to correct that because I don't want to feel forced to use windows, which I mostly hate for anything else, for that.
