Maybe I'm the exception, but I don't want checking out to be too easy:

- I like to type my credit card each time, I don't want sites storing it

- I don't want to accidentally click things and buy things I don't want (I click things a lot, just to 'see what they do')

- I want the buying process to require _some_ effort, so I only end up buying things I really want.

Of course it will require some efforts. I think the iPhone App Store purchase process handle it very nice, it requires enought effort but still makes it smooth and easy.

Usability and the most simple solution will always win in the long run.
