It isn’t much — but it is more than nothing. For the first time, Amazon.com is giving a hint about how many people are using its Kindle electronic reader and the apps related to it.
The online retailer says millions are reading Kindle books on the dedicated readers and on the free apps. While that isn’t the same as hard sales numbers, it does indicate of how many people have bought the Kindle. Amazon has never provided precise numbers about the number of Kindle owners or the number of e-books and other readable material made for the device.
