I have a Kindle reader with an E Ink display. It is much more pleasant to look at in daylight, especially when ambient light is very bright. Battery life is also much, much better. My tablet lasts two to three days at most, under light load, with power saving turned up to eleven. The Kindle can easily last one to two weeks. (It all depends on usage patterns, of course, but for my case those are the numbers I come up with.) I do agree, though, that it is hard for me to think of a use case other than an ebook reader. For that particular case it is perfect, though.
