As-is, though, I’m left with the nagging question ‘Why did the Nook need to be created?’ Each of the other ebook readers I’ve talked about has a perspective that makes it unique. But every time I think of the Nook, I think of a feature that another device does as well or better, or a feature that’s missing entirely.
