More Books Might Be The Answer
As an owner of a Sony eReader, I would suggest that the high costs of the readers and ebooks along with a limited range of ebooks would be a more likely cause of the stunted market. The last two books i tried to get in epub format weren't available (the new Chris Brookmyre and AC Grayling's Liberty In The Age Of Terror). Also, the pricing is ridiculous; £19 for an old Dick Francis? Anyone would think that the publishers didn't want ebooks to succeed!
