Stumbled into being a Linux Sysadmin after over a decade Windows work. Amazing how that old experience with Solaris, experimenting with Linux at home, and general willingness to use a shell can open up a career opportunity.
I still use Windows for my gaming computer. Android for phone/tablet. CentOS for the home lab. We even have a Surface in the house. So I'm generally a fan of using the right solution for a given use case.
