Plans are underway to spread the Kindle format, and open up access to the dedicated hardware, says Amazon's CEO. Speaking at a Wired conference, Jeff Bezos has explained that Kindle books should continue to sell for $10 as they go on sale through the iPhone plus "other mobile devices and other computing devices." A Kindle app is already available for the iPhone, though purchases must currently be made via the web.
Bezos also suggests that Kindles will gain support for more third-party formats, beyond unprotected MobiPocket files and generic types such as PDF or TXT. Kindles are primarily intended to read a proprietary format; Google recently announced plans to launch its own e-book sales however, which may have influenced Amazon's approach. In any circumstance the change could encourage adoption of the Kindle by people using competing readers.
