5561471 story Sony To Convert Online Bookstore To Open Format 107 Posted by Soulskill on Saturday August 15, 2009 @10:19AM from the who-are-you-and-what-have-you-done-with-sony dept. Dr_Barnowl writes "The BBC reports that Sony is to convert its online bookstore to the EPUB format. While this format still allows DRM, it's supported on a much wider variety of readers. Is this a challenge to the Kindle? It's nice to see Sony opening up to the idea of open standards. Even if you still have reservations about buying a Sony device, you might be able to patronize their bookstore sometime soon."
