It's not that installing Linux is a hassle. I just love a lot of the apps I can run on my Mac. OmniFocus, 1Password and DevonThink are two I have running now. I've also got OmniGraffle, Affinity Photo/Designer, Pixelmator and Keynote at least that I use fairly regularly (and I'm sure I'm forgetting some). I do a fair bit that is cross-platform and would work fine on Linux, but there are a lot of Mac-specific apps that are really well designed and a joy to use and I would miss them.
(And, yes, there are open source replacements for all of these that run on Linux. I know, but the UX is not the same!)
