Sony has officially unveiled three new e-readers, the Reader Pocket Edition PRS-350, Reader Touch Edition PRS-650, and an updated Reader Daily Edition. They all feature next-generation touch-screen E-ink technology.

It's not as attractive as the iPad, but Amazon's formerly derided e-reader is cheap and, most important, efficient.

Researchers at the University of Cincinnati have developed a method to improve the screen resolution and switching speed of e-readers.

Amazon has launched a UK version of its Kindle store today which has the majority of British bestsellers on sale in ebook form.

Amazon.com has introduced a new generation of Kindle. The all-new Kindle has a new electronic-ink screen in a 21% smaller and 15% lighter design, with 50% better contrast, 20% faster page turns, up to one month of battery life, double the storage, built-in Wi-Fi, with free 3G wireless, and is available for $189.

Giant online retailer Amazon is rumoured to be planning to give away free Kindle e-book readers to its Amazon Prime subscribers, something that could well boost its sales figure, both for the Kindle and Amazon products in general.

Amazon said Sunday that, while it still believes a $14.99 price tag for e-books is "needlessly high," it will have to give in to Macmillan's demands to sell electronic versions of its books at a higher rate than Amazon's usual $9.99.

Rumours that Apple's new e-book store wouldn't be available outside of North America when the device launches internationally later in the year seem to be proving true.

An Israeli hacker says he has broken copyright protections built in to Amazon's Kindle for PC.

Barnes & Noble alerts some customers who preordered the new e-reader that they might not get the device in time for Christmas. Company says it will send a $100 gift certificate, with apologies.
