I have spent a bit of time thinking about this, and can't really come up with a way of calculating a 'justifiable cut' for Apple. Would it be their cost per average app? Should it be a fixed fee with a variable rate on top? Should they license access like the videogame companies used to? Won't these smaller profits further incentivize Apple to offer competing apps in every category, and dis-incentivize quality control of third party apps? My conclusion (so far) is that it's best to let each platform developer choose their business model, and see which one works best. Business models can compete along with hardware and software.
