Audible has been an Amazon partner for quite awhile but I'd like to speculate for a moment about what this acquisition might mean in the long term. First of all, how might the Kindle play into this? Maybe down the road we'll see a Kindle that has this hybrid functionality built into it. Or, what if you don't own a Kindle but you'd like to have the audio version of the Amazon book you bought yesterday or last year? Could Amazon extend their Upgrade program to include Audible content as well?
Knowing Amazon, they probably have even bigger and better ideas in mind. Either way, I like the potential new product offerings that could result from this acquisition.
