Amazon just announced that it sold more than a million Kindle devices per week throughout December — that includes the Kindle, Kindle Touch, and Kindle Fire tablet. As usual for Amazon, no specific numbers were given, but the company says the Fire remains its best-selling and most-wished-for item, marking some 13 weeks that the Android-powered seven-inch tablet has held the top spot. The other Kindles didn't do so badly either: the Kindle Touch and basic Kindle were the second and third best-selling products in December, respectively. Amazon's foray into self-publishing also continues to yield success, as the number one and number four best-selling Kindle books in 2011 were published independently by their authors using Kindle Direct Publishing. All in all, a stellar holiday for the Kindle family, but we'd still love to see some specific sales numbers at some point.
