I have a first-generation Kindle Fire... well, had, as I gave it to my eldest son and got a regular Kindle because I only used it as a reader anyway, and the basic Kindle is much smaller, lighter, and lasts longer on a charge.
I found the Fire pretty underpowered, but that was just the first-gen model and the newer ones are supposed to be much better.
And the camera on the phone is astonishing. I am not a big cell phone user but we dropped our home phone so I got to have something. But I use my phone more for a camera and to read than anything else. Also to check Pinterest and keep up with the family on FB.
