In a recent post on Mashable, Josh Koppel of Scrollmotion whilst showing off some of his thinking around iphone / ipad interaction, towards the end he mentions that ,’the app is now the monetary unit of content’. So for example is $1.99 the correct amount for a celebrity news tracker, whilst Esquire on the ipad retails at a massive $4.99. It is also a change from the content/ad model to a content/application model. What are the interesting applications of your content that means the user will pay a premium for it?
