$">$1700$2. $ 800
The iPad Mini starts at $329 from Apple.
The iPad 3 starts at $499 (US).
An Amazon kindle costs 199 dollars. The kindle is an amazing turning point in the human society. I enjoy mine very much. You can download free apps ( applications) and books. Or you can rent a book from your public library. Did I answer your question.
Actually, They are pretty much the same. You can read, download books, watch movies and videos, play games, and do much more just like the ipad. The good thing is that the NookColor is cheaper than the ipad. I know because i have one.
