Since we’ve criticized Amazon before for not reporting Kindle sales figures, I should link to the closest the company’s come to transparency yet:
Amazon.com, which generally never talks about how its products are doing beyond the vaguest terms, issued a press release Thursday saying it was selling Kindle e-readers and tablets at the rate of a million devices a week for the last three weeks.
Note that’s all Kindles, not just the tablet Kindle Fire, and that it’s December 15.
