I never really thought e-ink was a great solution for readers. About all it really has going for it is low battery consumption. Some folks really like the print quality, but I find it slow and low-contrast-y and.
That's why I really like reading on my old Palm device or netbook. Sometimes I really like to change background/type colors. And page turns are so fast I don't always see them.
I ALWAYS see the page turns on my Sony.
