The reading screen on this second-generation Kindle is on par with the Nook's, but navigating is trickier (look at all the buttons!). Amazon offers a nice selection of blogs and periodicals. But while it often has the best prices on books, it offers fewer titles than Barnes & Noble. Plus, you can't access as many free books as on the Nook because the Kindle doesn't support the EPUB format.
