E-book sales beat print sales at Amazon
The Kindle online store boasts a library of 390 000 digitised books, which can also be read on Apple iPhone or iPod Touch devices.
Amazon has not released figures for Kindle sales, but Forrester Research, a US-based independent technology and market research company, estimated in October that the Kindle has a nearly 60% share of the US market, followed by the Sony Reader with 35%.
The Nook, a new device sold by US bookstore giant Barnes & Noble, is also competing with the Kindle.
The company said it sold all of its Nooks one month before Christmas, and that the next shipment will not be available until early January.
