Doug:I don't quite grasp the fact that it's free to
download off the internet though, as the functionality I have is
exactly the same as the functionality I use/ed in windows yet no where
have I paid for anything.

I don't know that
anyone "quite grasps it", Doug! But the plain fact is that the
GNU/Linux/Open Source movement has since Day 1 made the results of its
efforts freely (both free of cost and free of restrictions) available
to all.
SuSE, Red Hat and other companies making a living from
Linux have got their profits from "adding value" to the freely
available software -- by putting it on CDs and providing printed
manualswhich you can buy (pretty cheap) in a box, by offering a paid
support service, by overseeing installation and system maintenance for
other companies whi decide to "go Linux", etc. More recently there have
been tie-ups between Linux companies and other big operators, such as
between SuSE and Novell. Don't forget that "heavy" computing has
traditionally been Unix-based (DOS/Windows couldn't cope with the load
and efficiency requirements until, possibly, quite recently), and so
e.g. database software firms like Oracle and Informix have also
supported Linux since this helps them enlarge their own market. And so
on.
At the same time, setups like Ubuntu continue to produce their
stuff in a more "pro bono" spirit. And there are thousandss of people
who donate their spare time to develpiing Linux and applications to run
on it; many of these do so as a spin-off from their "day job"--just
have a look at for instance
http://www.r-project.org
to see
the constellations of academics and industry professionals who clearly
contribute vast amounts of time in this way. This of course benefits
their employers as well.
