The book FLOSS Concept booklet http://wikibooks.org/wiki/FLOSS_Concept_Booklet is at the verge of completion. But I need some help with the following.

1. List of popular distributions that come with non-free software. 2. In the question "What kinds of problems might I expect to encounter using free software?". Write about inability to play encrypted DVDs? About the DMCA??? 3. The answer to the question "I'm still not convinced. Surely a big computer company knows best when it comes to designing software? Why would I want to use software designed by an amateur?" has gathered a lot of meat. Can somebody summarize it? 4. There are some questions on Digital Commons. Does anybody have answers for it?

If there are any questions that might be useful for newbies please do add it...

Regards, Vijay
