<human>: Which is a better choice: a Kindle or a Nook?
<bot>: The Kindle has the advantage of being able to download books directly from Amazon, whereas the Nook can only be purchased from Barnes & Noble. However, the Nook offers more features and options than the Kindle, such as access to the B&N library of eBooks and magazines. So it depends on what you are looking for in a reading device.
