Are we talking the ToC at the beginning of the book that I have to flip through to get to the actual stuff I want to read? Or the internal one?
Printed ToCs need to die. I can always use the "Go To" function on my reader to go to whatever chapter I want.
I'm a big fan of having ebooks go from Cover (a SINGLE cover) to reading material; put all that extraneous crap at the back of the book.
