Android
is a Linux. Not just in my humble opinion, but two of the
most important sources:
"Android is a
Linux distribution according to the
Linux Foundation,

You're guaranteed to get arguments about that, but...whatever! Having used UNIX and then Linux for 35 years, I know a *nix system when I see one. I'm typing on one right now--my Android phone.
Everything you want to do on your Kindle, and then some, are doable on my Kindle but, as I said, I rooted it and turned it into a regular Android tablet. I strongly disliked its UI, and really disliked not being able to use the apps and features I knew it could support...if not locked down by Amazon.
I don't agree with you, however, that Amazon sucks. They put out a line of products with a distinct purpose in mind, and the products do that well. But for someone like me, who wanted a real Android tablet, it just wouldn't do. So I changed it.
