I think Microsoft have missed an opportunity here. They could have incorporated the Nook into the never released Courier so that you had an e-reader that looked like the two pages of a book.
Also with dual screens you could have had a traditonal one page e-reader open and a traditional tablet style on the other. It could also have been used in laptop mode with an onscreen keyboard and display.
Such a product in a size of around a 10" display would have had me interested.

That's a really interesting idea, Myss_tree. I would be interested in a double screen tablet that could be a phone , too, if they used 6-7“ screens. One with 10” screens would be a really great tablet and could be used as a laptop. Pretty ingenious if you ask me. :)
