The assumption is that the integration of those apps into use-patterns closely enough resembles what they do on the iPhone/Pad. The reality is that it's mostly people who have a predilection towards experimenting with technology who will switch. I doubt that user group makes up more than a few percent of the consumer market.

Apple, I'm sure, studies price patterns and knows well how far up they can push a price without losing the core of their market.
