That depends on which distro and hardware you're using. I use laptops that are known to work well with Linux and Ubuntu LTS releases. This way, I spend perhaps 3-5h a year on admin tasks and it's mostly easy stuff.

It's actually amazing how GNU/Linux allowed me to gradually transition from configuring everything (when I was a student: XFree86, custom kernels, ...) to using GNU/Linux productively with almost zero housekeeping effort.
