We switched an entire team of about 10 people to Ubuntu just because we couldnt afford to buy any more Windows licenses. The only thing the team missed was Office and had a few issues with audio/video plugins for the browser which we solved mostly without any headaches. They re now happily using Google docs and Open Office.

Unfortunately, we are a race of habit and being served tea instead of coffee every morning is gonna piss us off but eventually we ll get over it.
