Since MorphOS is supposed to be a free system shipped with every Pegasos sold I really think we should make it affordable to everyone. Americans can say that 50 USD is nothing for them for a major release, however 50 USD in Eastern Europe or Asia can be ALOT. The best way would be for each User Group in each country, or some trusted individual* who can calculate what the people of his/her country can afford.
We in PUGS would be happy to discuss the costs for Swedes.
* With "trusted" I mean someone who has a pretty normal wage, the experience of, or have a clear vision of it. Some millionaires do not. :)
