we are looking at the Fire to upgrade our daughters older Kindle....I looked at all of them and none of the newer ones seem to come 3G.
I do know that when the screen on her old Kindle went bad, we called the 800 number and there was no hassle with the warranty, the replacement was sent the NEXT DAY...they have great customer service IMHO
The Kindle Touch and Kindle Keyboard both come in 3G variants. I know, because I asked Santa for a Kindle Keyboard 3G for Christmas :)
The Kindle Touch’s 3G is gimped. All you can do with it is access the Amazon store and Wikipedia. With the Kindle Keyboard, you get full access to the web. The downside to the Kindle Keyboard’s 3G is that because it’s not a touchscreen device, navigation is somewhat more cumbersome.
