Tom, true, you know what's even worse about the Adobe pricing scheme? You could fly first class the the US, stay in a hotel, buy CS4, and fly back, for that very same price as buying it in the UK/europe. I dont know how that is know, but a few months back this was a realistic look on things.
Also, a realistic look on the public domain, copyright, and some historic development on this subject can be found in these PDF's, i finished the free culture one recently, i think there a good reading for anyone that wishes a better understanding about copyright and the oligopoly market on movies/music.
