Maybe I'm just negligent, but I do have a remote server I spent a full week configuring (web, and mail, just for me, from ssh). I'm no sysadmin, I expect a good one would have needed no more than a couple hours. But I haven't touched it in
months. It just works. (Or not. Lack of updates may have lead to vulnerabilities.)
At this point I doubt we mean the same thing by "administration". To me, it means updating the system, fixing what doesn't work, and installing new programs. Spending en entire hour per day just for this sounds insane. Perhaps you had other tasks in mind?
Also bear in mind that I'm currently using a "long term support" release of Ubuntu, on hardware I knew would be well supported (I've read a couple reviews). It's not Arch on a random laptop.
