Mossberg, un tech-guru, dice del Nook: "I don't think it's as good as the Kindle, at least not yet. At launch, the Nook has the feel of a product with great potential that was rushed to market before it was fully ready. [...] During my tests, I found the Nook slower, more cumbersome to use and less polished than the Kindle. I ran into various crashes and bugs. And, while the Kindle's navigation system isn't exactly world class, it ran circles around the Nook's, despite the great possibilities offered by the latter's use of the touch screen."
Il resto, qui. Per chi avesse ancora dubbi, direi che il discorso si possa chiudere qui.
