Marco.org has a comparison review of the Kindle 3 and Nook Touch. Overall, Marco Arment, creater of Instapaper, really likes the Touch. Here’s a snippet:
Overall, I’d classify this Nook as being a generational equivalent to the Kindle 3, but the Kindle 3 is nearly a year old. Launching an equivalent competitor to it today is like launching an iPad 1 competitor in February 2011.
I’d be much more impressed with this Nook had it launched last summer, and it worries me that B&N is only now using the same e-ink screen generation that Amazon had then. (What will the next Kindle use?)
But I like it. And I love the touch interface.
If the review ended here, I’d probably conclude that the Nook is a great alternative to the Kindle for nearly all potential buyers. But these e-readers aren’t self-contained — they’re primarily vending machines for two very different publishing ecosystems.
In a heavily ecosystem-dependent category like this, one good hardware release isn’t enough. …
The Kindle wins here, hands down. Amazon’s store has noticeably more books, newspapers, and magazines that people are likely to want. Many titles I’ve searched for aren’t available for the Nook but are available on the Kindle, and I haven’t yet found a case where the opposite is true.
Furthermore, Amazon’s DRM really hurts experimentation: I can’t transfer Kindle books to the Nook or vice versa, so now that I’ve purchased Kindle books, I’m strongly encouraged to stay with the Kindle device family.
While this will matter to very few Nook owners, I can’t use Instapaper or any other online service to send web content to the Nook: there’s no document-delivery mechanism like Amazon’s email gateway, and no web browser to download files directly. The only way to get non-B&N content onto the Nook, as far as I can tell, is to transfer it via USB or a micro-SD card.
If you own an iPad in addition to an e-reader and want to run the respective Nook or Kindle iPad apps, you’re much better off with the Kindle. The Nook iPad app works, but it’s mediocre, while the Kindle app is excellent.
