Putting this here while I search for a better space. Also wiki.kde.org is down with a database crash.
A blog post by Nikolaj Hald Nielsen about Amarok 2 on windows sparked replies from Aaron Seigo, Derek Kite and Christian Ehrlicher as well as a lot of people commenting on these articles. In fact, this topic has had great response in 2004, when Aaron Seigo asked "how to kill the open source on the desktop?" and received roughly 170 comments. This page tries to present an overview of the arguments as well as an outlook on challenges and possible strategies. I will also post all the open questions that came to my mind. Enjoy.
