Part of me was waffling on this for a gift for my father. On one hand, I'd like to make it easier for my father to get the books he wants for it and the Kindle seems to be good for that, both with selection and ease to find books. On the other hand, It was hard to justify the $100 premium for it for that reason.
This price drop puts things into the same ballpark. I still don't know if it is something I will get him. (he wants a reader that scrolls text automatically without him turning pages)
