My colleague Simon, who is self confessed suit-compliant human, was pleased to be able to install our Open source product without problems in an hour on our server.
I think this illustrates a trend that has been evident for some time -- Open source software is now ready for the mainstream and can be used by anyone. To be sure there are bad examples of the art, however that applies across the whole software industry unfortunatly.
Can world domination be far away? :-).
