War and Peace, Anna Karenina, any recent book by Neal Stephenson - those are all much more pleasant on a kindle than in paper form.
Well the iPad weighs 1.3 lbs, and the Kindle weighs less than half a pound. Only the smallest paperback books are lighter than a small ereader.
Like those old serials, The Executioner and The Destroyer. Gotta love those old, < 100 page bubble gum books.
My biggest problem was always trying to hold a book open with one hand. This was a problem because my hands are large and trying to read a paperback with both hands was sub-optimal, not to mention reading in the bath or whilst lounging.
Which is why I have a Kindle eReader and an iPad.
I agree that the eInk Kindles are one of the best bits of tech I've ever owned and the best reading experience I've had.
I can lean a Kindle against the pillow, which is much harder to do with a book.
