Also you have to realise that the the computer owning public has changed. The people who in my quaint 20th century terminology, had flashing 12:00 on their VCRs (I can hear my kid now: daddy, what's a vcr?). These folks, the flashing twelvers, own computers now. They can barely use a Mac or PC, they would be totally lost on an Amiga.
It isn't that you are dealing with less creative people, it's that computers are like automobiles or refrigerators, everyone has them. Amiga users were a preselected crowd in a pre-selected number of computer owners. The same percentage of human beings are creative, the distinction is no long what computer they own or if they own a computer but what they use their computer for.
