Yes, to a degree the index is redundant in e-books but for the reasons outlined by ATDrake it is still useful. A good index is like a curated search: it should point you to the places in the book where the term in question is most relevant. Sometimes an index will break down a term by context. Using the search function can be pretty slow in a large book. Finally, if the publisher is going to include an index in an e-book then it *should work*. I don't think I'd have so bothered by a missing index, but a broken index is just taking the mickey.
