I know they sell the Nook devices which are currently the main competitors of the Kindle devices, so I'm guessing that they probably will.
3rd party sellers sell the Nook products on the Amazon site, not Amazon themselves. I assume it'll be the same with the Nexus 7 since only 3rd party sellers sell the Galaxy Nexus (GSM version anyway. Amazon Wireless will sell you the Verizon and Sprint versions).
Yea amazon has never sold an iPad but they have pretty much every other tablet on there. Would be awesome if they end up selling it. I'm still debating whether or not to get one as I have a fire right now
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
