Right.  It implies volume.  That was the only point I was making.  If

I am also politically neutral and have not voted since I was 18 as a

For me, if I was going to start a company, Linux is a technically
superior solution for a server in my view.  This is especially true due
to license reasons.  If I want a thousand users on a machine, the cost
for a Windows solution dwarfs any reasons I can think of not to switch
to Linux.  However, if a company does not have personnel trained to
administrate Linux machines and applications, then something else might
be a better choice for them.  ("Fire all your workers and hire new
ones." does not work)

Then for those customers for which it is the best choice, you would give

FACT: Every blanket statement is an over-generalization.

Microsoft has done some very seedy and evil things.  The destruction of
STAK comes to mind.  As far as domination by giving things away, that is
ludicrous.  You can download Linux and most Linux applications for
nothing.  In essense, they give everything away (really, you are buying
service when you purchase a Linux CD) and MS has to compete with 'free'
-- not just for the tack-on stuff but for the entire system and all the
applications.  It shows you how well done some of their stuff is, that
it can compete in that arena.

I have had to deal with many things that were unpleasant and caused
directly by MS doing something strange or bad.  I have lost days of work
because of it.

I don't even know what 'Go Computing' is, so you are right about that

It must be nice to be young and still see everything as black and white
with no shades of gray.  For those who think that Windows should be
canned, Gates should be burned at the stake, and Linux should rule the
world, I have no problem with their opinions.  We all get to choose what
we like and dislike.  I think that the typical Linux fan is WAY over the
top both in seeing the advantages with rose colored glasses and turing
opposition molehills into mountains.  But passion is good, and I like to
see it.  If it were not for the passion of the Linux crowd, there would
be a far less interesting competitor for MS and a far less interesting
toolset to use with it.

Maybe the thread should go to some advocacy channel at this point.

My reason for jumping in was to show that:
1.  PostgreSQL will have a exponential leap in possible sites when it
opens up to Win32 systems
2.  There will be huge installations on Win32 systems, like it or not.

Some other things to keep in mind:
1.  The average Windows user is far, far less computer saavy than a
Linux (or other flavor of UNIX user) and hence, there will be a big load
of "deer in the headlights" users coming on board.
2.  On the plus side, there are millions of good developers familiar
with Windows.  Some of these may become involved with the PostgreSQL
project and give added value.
