ah... yes... well... though i admire your enthusiasm to propogate new theories about 'prosumers' & 'recreation of content'... your points are best examples of academics who study a microsegment of the world and theorists who sell corporations new magic formulae.
most people who buy ferraris or armani suits or ipad-like devices buy them because they are status symbols of success and coolness, as displayed by a famous actor wearing the suit, a successful businessman driving the ferrari, a tv personality holding up an ipad.
you're not going to tell me that they're handing over cash because they have been influenced by "user interactivity with the information and recreation of content," or "total new environment for the travelling and transformation of information", are you?
they buy because it feels good, because it's useful for daily life or because its a sex magnet. the internet has not revolutionized 'why people want something' it's just another channel to get attention.
i do like stimulating thoughts on how the world works, but yours are the thoughts of someone living in an ivory tower with a microscope and a thesaurus.
Actually, i'm one of those people who get the things free just to wear them, so i'm quite aware of those mechanisms
