What's a fair price for an ebook? (POLL)

If one question has kept popping up this year, it has been "What is a fair price for an ebook?" Publishers have been putting their case for the prices they're asking. Writers have been explaining how cheaper ebooks are boosting their sales. Readers have been asking why there aren't bigger savings with no physical product to make, store and distribute?

So I've set up a poll on the Victor Finch Book blog, here, to get as many opinions as possible on what is a fair price for a digital book. Please take part and tell as many people interested in books and reading as you can.

Thanks.
