Interesting, I'd love to see a source for this claim. I've long wondered why Adobe make their software so insanely expensive, thus effectively guaranteeing that the only people who will pay for it will be professionals. For some reason, it didn't even occur to me that it might actually be a deliberate part of their business strategy. Rationality fail :(

This might also explain why they offer the software free for download on their website as a 'trial'.
