The very first in depth of the Literati was posted yesterday in the New York Times. If you're wondering why I didn't get it first, well, as great as I am I'm not the NYTimes. The reviewer had some fairly good insights into the design of the Literati:
To turn the page, you use left and right buttons positioned on either side of the screen, but I found the placement odd (some competitors have the same configuration). To go back, you push the top button on either the right or the left; I expected the page forward button to be on the right, and the page backward button on the left. Instead, there is one of each on both sides. But that prevents the reader from holding the device at equal height with both hands.
The rest of the review is worth a read.
