I am most interested in what you perceive to be a road block or problem that keeps you from using Linux.

I'm highly experienced with Linux and BSD to the extent of setting up and managing web servers for clients and myself. But I still use a Mac as my primary machine.

I've been tempted to change, mostly based on the desire for a wider selection and greater affordability of hardware without the "Apple Tax;"while the build quality of their machines is still very good, they keep adding useless features (the Touch Bar) while removing useful ones (USB-A and HDMI ports on laptops) and constantly trying to make hardware thinner and smaller even when it's desktop hardware. And I still might change some day. But for now, it has all the software I want (save for a few games, but I make do), including all the Linux/OSS-ecosystem stuff as well as all the Mac stuff, and things like my music collection, contacts, calendar, and such integrate well with my iPhone (I sure as heck ain't going to run Google's spyware phone OS and I'd have the same issue with a Windows phone).
