Hows that Kindle Touch?
My Wife just bought a Kindle Fire. Looks pretty cool but I doubt I'll ever get my mits on it since she bought it to use for her grad program.
If you're wanting an e-ink kindle, get the original. The touch is kind of wonky...not nearly as smooth operating as the original. The fire is cool, but I'm not big on reading on the back lit screens.
We have a nook color, and it's okay for web browsing or reading magazines...but I've only finished one full book on it. My eyes would hurt after a while reading on it.
