double screen ereader
high-end eink ereader
As a book lover and reader, there is something I dislike about the tablet shape of actual ereader's design : it is too close to the various electronic devices made for entertainement. A book is composed of pages, and you have to read the first, then switch to the second. It creates a continuity in the text and in the process of reading, which is important to follow a long and complexe reasoning. The tablet shape doesn't show this continuity, making the act of reading feel like navigating on the internet, which is very different.
The double screen ereader bring back ereading in the world of books insead of technology.
