Well, there is the chicken/egg analogy. You could argue that there are no professional designers using Linux because there is no professional software. Perhaps there would be many designers using Linux if the existence of professional software would make it attractive enough? Sometimes the supply determines the demand, not vice versa. The same argument can be brought up for public transportation: if people are using their cars because no public transportation is existing, how can you know whether people will or won’t switch unless you first establish a supply?
