Today Gizmodo, posted a review of Seiko’s new e-book reader, next week Amazon is launching their e-book reader, and there are rumors that Borders will be partnering with Sony on a co-branded e-book reader (in typical Borders fashion).

These various products cost at least $300, so they aren’t a bargain. And I don’t see the appeal of having to carry around another clunky device. Instead, e-books should just work on a laptop, iphone, blackberry, ipod touch — and not require a specialized piece of hardware.

Given the high quality reading experience on the iphone, I would be surprised if Apple hasn’t at least had preliminary discussions with the major publishers. Not that I’m dying to read books on my iphone, but why not make it an option?
