While doing some more research about the Nook Tablet, I came across this article.
It discusses the different features of both devices and examines to see if either can make a suitable alternative as a tablet to the IPad 2. In the end the article puts B&N up on top over the Amazon, but only slightly. I think this article is a good starting off point in finding out the specs you are looking for in a device.
This article is also related to the post I put up about how E-readers are supposed to be E-Readers first and Tablets second. I know if I lent out E-readers at a library I would much rather them use the devices for reading and not just watching movies and downloading songs. Don't get me wrong, I do think libraries should have all these mediums, however, with funding the way it is right now I would rather all the available space in the E-readers to go towards texts. There are already plenty of mp3's available in most places as well as digital video. Getting E-books that are still under copyright are a whole different story.
