Much to no one's surprise, Amazon did not tell us how many Kindles or Kindle Fires they sold, but they did report that they sold "millions" and that Sales were up 177% over the same period in 2010. Of course, back in 2010 Amazon had just the 3 Kindles, while in the last quarter of 2011 they had no less than 7 models on the market (not counting the ad-supported). So the increase in sales isn't nearly as impressive as prior reports.
But while they didn't say how many KFs they sold, there was a footnote about the Amazon Appstore. More apps were downloaded during Q4 2011 than the previous 3 quarters combined. I'd say that is lrgely due the the KF, considering the app news I reported earlier today.
