- you mean I can't view my publication on any computer, even a Mac?
- you mean that if I want to sell my publication, it has to be through Apple's store?
- you mean that Apple wants to be the sole provider of textbook delivery?
Now I am thinking that it is almost a moral imperative to take a pass.
Having an easy application to create digital materials is a wonderful idea. Forcing those materials to live in a proprietary format, available for sale in an exclusive Apple store is not. Isn't that what Steve Jobs said he didn't like about Flash?
I guess I agree with dougpete (with thanks for the links).
