Hi Paul,
I completed your survey because you asked nicely
. However, I felt you should have added the option 'I wouldn't read an ebook by serial chapters and would never pay for them'. Otherwise a poll of the ereading public might wrongly suggest they would all read a book in that format and the only thing to settle is the price and frequency of chapters. I may be wrong (and your survey results will give us a clue!) but I think that is a long way from the reality.
Good luck!
Chris
