I'm a long time Kindle user. I love them all. That said, the FIre sucks for just above everything. I'm not a techie person, but to me, it is a classic case of a machine purposely made on the cheap that is designed to do a bunch of things "okay" but none of them really well. However, the user experience, especially if you have even passing experience with an IPad, leaves you feeling like it does a bunch of things poorly and nothing at even an "okay" level. Reading is not as a good as a regular kindle. Web browsing is not as fast as a 3 or 4G smart phone. Reading magazines is awkward because of the way they load and appear in the frame. One positive for the future is the linked relationship between the amazon cloud storage and teh device. And music purchased from amazon is playable on apple devices, because they don't embed it with the code that prohibits cross playing. But other than that, it just fall shorts on almost every area.
I've had a chance to play with all models by now.
Fire is, as I'd imagined, is a generic Android tablet sold at about $100 to $120 discount. So you're buying the same crap everyone's selling but at least you're getting a subsidy.
Touch, surprisingly, features a substantially worse (lower contrast and, at least it feels like, slower) display and is less convenient to hold than the previous generation.
The keyboard version remains the best product if you're looking to read a lot of text and find LCDs tire your eyes.
