If you do any type of poll, wouldn't most people that answer for any platform be existing Pleco users and mostly interested in license transfers? I don't know if that would be the best way in figuring out where new potential business will lie.
I think you may be able to make more money supplying more, smaller,focused, but less complicated products, compared to large, more expensive and complicated products. For instance, I think a putative Anki iPhone app would sell a lot more than a spinoff of Pleco's current system, even though the latter may be more complicated. Anki focuses on one simple model, but focuses on doing it elegantly and just telling users that the scoring system "just works." Many users are happy paying $5 for a simple dictionary running CC-CEDICT.
