Thats a bit rubbish, not to play devils advocate but maybe its a way to generate more money by making you get some documentation off them?

On the other hand, there was a discussion at uni about having electroic manuals (such as the help files as they are very concise) over paper based ones as if you were buying a highend computer software you would (probably) know how to operate a PC and find the help files.

For the price you pay for the programme there at least should be some sort of paper documantation to give it some weight, as you pointed out.
