This piece by Bruce Byfield sparked my interest a bit, because the topic of world domination, is one that keeps me up at night. Specifically -- how can Linux edge closer to a majority market share, particularly on the desktop?
When you're trying to provide a system that is appealing to former Windows users, you generally find that a lot of people expect features that are often only available from proprietary drivers, codecs, or applications. So, the question is whether Linux vendors and projects should supply proprietary software in one form or another to address those needs, or to insist only on free software.
