There's no shortage of headline features for Amazon's third-generation Kindles - new, lower pricing, the inclusion of WiFi, E Ink's updated Pearl display - but there are quite a few quietly tweaked additions that could promise an even more interesting future. A Kindle World spotted the inclusion of a microphone - currently unused - together with a few other tidbits, that has already prompted some to suggest a voice-enabled Kindle could be on Amazon's roadmap.
To our recollection, this actually hasn't happened in quite some time. To be exact, in 2008, when it was the original Kindle. And, even then, Amazon managed to make sure they told customers when the Kindle would be coming back around, or shipping to their doorsteps. Not this time. All Amazon says right now is that the Kindle is temporarily out of stock, and that purchasers will get an email when the eReader gets an estimated delivery date.
