Seems like a very good scheme IMO. With all the hype about Anki and how good it is lots of people will want to try it out. After finding out that it actually is good they might want to use it more frequent i.e. on the iPhone. And then they'll most likely buy it despite the price. I know I will, anyway. And since Anki is open source and free I feel that the price will keep him motivated to improve on all things.
