So I posted a thread in the CrackBerry forums to get a general feel and opinions on what people thought about the current App World pricing structure (specifically for the PlayBook… I am sure the same apply to the smart phone App World also).
Before I start, let me give you a quick low down on how the current pricing structure works.
