Well it was a rather silly post comparing apples to oranges but it did contain a useful number of 1300 to 2000 OS4 users. Would you say there are a similar number of Morphos users?
Given that we are dealing with a few thousand users wouldn't it make sense to combine forces and develop for both? Even then it would be hard for a developer to actually earn a living. But tearing each other apart is suicidal...
