BTW the numbers that I was throwing around above represent only the revenue side, based on the clearly ludicrous assumption that somehow Gravity wouldn't need advertising. There is no way to get thousands of users without marketing. This is part of the cost per install (CPI), currently $3-$5 (actually higher for more involvement, e.g. registration or purchasing, but let's be generous here) and rising due to the increasingly competitive market. So does ionomy have $200k+ to spend to get those 75k users? We'll find out on March 25.
