"Most people don't associate customer support with Open
Source, thinking that with free or open source software you get
what you pay for (nothing). As we have seen in our
experiences with Linux and free software, this couldn't be further
from the truth."
"The authors of these programs are usually very protective of
their work and want to see it flourish. This is why questions to
them about their software are usually answered very quickly and why
bug fixes can be implemented even quicker! :) Imagine calling
Microsoft and asking to talk to one of the developers of Windows
because you found a bug you wanted fixed."
"Another great thing about open source software is that you can
truly try before you buy. You can download the software (in binary
or source code) configure it and see if you like it. If you like
what you've found you can often buy support for less than what a
comparable closed source application would cost."
