Can someone explain to me why an e-book reader is more useful than a book, an audio book or just a .rtf file on your phone?
Because everything I've seen seems to say to me that it's less useful, easily steal-able and you only rent the books?
1) Audio books are a matter of taste. If I go blind, I might appreciate them. Until then, my preference is text. If you are able to speed read, or even just fairly literate, you can read faster than someone can talk.
2) Books clutter up the place and weigh you down when you are travelling. If you are vaguely interested in several books, you must choose one or two before travelling and not on the journey. Some books are offensivley bulky on their own eg Bible, War and Peace, Encyclopedias etc.
Books are not necessarily available in large print, while all ebooks can be displayed in large print. Ebooks can be obtained immediately from the comfort of your own home, while you must either go out and get a book or wait for it to be delivered. Although you cannot currently save money with an ebook reader unless you read hundreds of free ebooks, if prices drop the way they did for mp3 players this may change.
3) Ebook readers use E-ink/E-paper. It looks like a printed page under glass. It is readable in bright sunlight and draws little to no power on a static display. Other portable devices use illuminated displays which are only readable in sunlight with the brightness turned up, at the inevitable expense of the battery. PC monitors cause eye strain, while an e-paper display doesn't, because you are not staring at a light source.
I think there should be more e-paper displays, to save office workers from eye strain and text addicts from flat batteries. A device like the iPad with an e-paper display would be pretty cool and would make e-readers obsolete. Until then however, the ebook reader is a useful device.
