I am employed as a support engineer and a sysadmin, and I still run in to driver issues, printer issues, etc.
I take care of them, eventually, when I can.
But, even after doing this for 10 years, I still encounter problems that I can't solve (because there isn't a solution.)
but the metaphor of Apple as sysadmin, I'll accept. I disagree with someone else admining my phone, but that's another issue.
