I mean that practically the only buttons required on such a device are the buttons to turn pages (maybe some modifiers to swap between books and to go to the beginning and end of the book). Other buttons are superfluous to a "back to basics" device.

What I'm saying is, the Kindle has too many features and is too expensive.

The Kindle needs that. Its top, ignored feature is its ability to download books from anywhere from the Amazon store. For that it needs a navigator, a keyboard, and wireless Internet access. And from my uses of the device, that's what puts it in a league of its own.
