The sites that have free Kindle books daily (Ereader News Today and Pixel of Ink) have gotten me interested in different authors and genres than anything I would've previously read. Since they are FREE, it's definitely worth the risk. I've only disliked one or two of the MANY free books I have downloaded for my Kindle.

I'd like a bigger tablet with more features, but for 200 bucks, this works well enough.
DD watches Netflix and Amazon Prime video on it, works well!
Another good thing about the Fire? Since it's just a little Android tablet, you can read other formats on it. Sometimes you have to go around the Amazon Android store because they have blocked things out, like Aldiko, which is an epub reader, and Dropbox, which is storage.
By going around Amazon, I can read my entire (enormous) epub collection. And PDFs and what not, of course. PDFs, you just have to use landscape and have good eyes.
But I have to admit, the Nook tablet I got after (because my daughter works at Barnes and Noble and convinced me it was de rigeur) is a pretty nifty device, too.
I find I use the Nook for totally different things than the Kindle, though---for magazines (which have nifty interactive things, such a music samples in the music review sections, and animated demonstrations of exercises, etc), for the 'net, and for Netflix and Hulu and such.
I do like it for reading books, but find the Kindle easier on my eyes.
I was sitting in the pick-up line at lilbeast's school and pulled out my kindle to read until school let out. As soon as I turned it on, I get the "battery empty, recharge 30 minutes" screen. NO previous warning that the battery was low. I never had to re-charge my books.
If you have a smartphone with a reasonable data plan and don't want to pay those pesky tethering fees, you can turn your phone into a Wifi hub with a few free programs. I use Foxfi.
