To compete with the Nook, the Amazon Kindle patches some holes in its feature list.
As shoppers draft their holiday wish lists, Amazon made a move today to nudge potential e-reader buyers into asking Santa for a Kindle.
A free software update will now patch up one of the frustrating holes in Kindle's feature list and increase its battery life.
The e-readers can now get up to a week of power when its wireless antenna is turned on. Before, Kindles lasted about four days. This update makes the wireless features more energy efficient, so there is not a similar boost in the two-week battery life enjoyed when the connection is turned off. Kindle's chief competitor, the Barnes and Noble Nook, will run for 10 days with wireless functions disabled.
Amazon also added PDF support. Earlier firmware required Kindle owners to convert PDF files into a proprietary format – where as the Nook, Sony Reader, and the larger Kindle DX could display PDFs without a hitch. This helps ease comparisons between the three leading devices. But Kindle still does not recognize ePub files, which Google uses for its half-million public domain books.
