Mycropht,
I feel your English is quite good, and you made yourself clear. I wouldn't equate the Reader with the iPod, either. However, it has made definite strides, and shows that a p-book-competitive e-book is much nearer. I think that an iPod-like reader could be made using E-Ink, but I think it needs to double (or treble) the screen area, double the resolution to 300ppi, and add search capability. At that point, it will be able to
surpass the p-book in usability. Toss in notetaking features, and e-book will not just have "arrived", but will have
colonized the media landscape.
To compare it to colonization of North America, the Sony Bookman was a failed colony (Roanoke), the Rocket eBook was the first successful colony (Plymouth), and the Sony Reader will be a more successful colony (say, New Amsterdam or Philadelphia). If I compared it to the US's historical timeline, we have passed 1620, but we haven't reached 1776. With the Reader, we'll round 1700, getting us halfway to full establishment.
(Hopefully, I haven't stretched this analogy beyond the breaking point.
