It is a misconception that mainstay Linux distributions have any sort of hardware or software incompatibility (aside from Mac- or Windows-only targeted software). That said, you are correct that people use OSX because it's literally 0 set up and configuration.

There's a lot of incompabilities on new hardware. Usually Linux kernel needs about 6 months to catch up with latest Intel or NVidia products. Also, try to use an iPhone with Linux computer - it is a nightmare. I have Windows installed in VirtualBox vm solely for iTunes's sake.
