For Christmas, I received a Kindle Fire. I'm quite enjoying it, as it's roughly the size of a paperback (which means easy transport) but can hold an innumerable supply of books (Between the cloud and it's storage capacity)
One of my friends on Facebook shared a resource with me which highlights some of the best deals on Kindle as well as Amazon Apps and books for the Nook. Some of which are free, others which are good deals.
The site is Pixel of Ink.
For those who have a Kindle Fire, you can find a great forum specifically for the Fire, from troubleshooting issues to apps and books. You'll find the link here.
