You have to learn to walk before you learn to run.
You are right; A lot of the tools you will need to use on a day to day
basis as a *nix sysadmin are not common in the home. What is common
though is the comfort level and familiarity with the fundamental system.
"Linux on the desktop" does not matter in this case because Paul wants
to be a Linux sysadmin, not take over the world. You can very handily
live day to day with Linux as your primary OS. I've been doing it for a
decade solid and I am lacking nothing but some modern games.
I do have to disagree with the "familiarity on windows has you most of
the way to understanding Linux" argument. They are very, very different
beasts. Take any application and look at how they are configured on
Windows vs. Linux; dhcp, web, firewall, dns, etc... Look at how you
setup a bonded network interface vs a teamed interface.... so on and so on.
At it's most fundamental; POSIX's idea of "everything is a file" makes
it drastically different from the Windows environment. Once you start to
get a feel for piping commands, command-line parsing and text
manipulation, logic and variables... you can hardly compare it to MS
command prompt or even power shell.
I'm not interested in arguing which is better, that's an argument for
another day and several beers. My point is that Paul will have a lot to
learn to become a Linux sysadmin and the first step is to get
comfortable with the basics. To that end, nothing compares to switching
your daily computer to Linux only. You need to jump into the deep end to
force yourself through the learning curve.
Linux is not hard, at all, but it is different.
