As rumoured over the past two days, Amazon has unwrapped a super-sized version of its e-book reader.

The new jumbo-size Kindle Deluxe (or DX) has a 9.7-inch (26cm) screen, which Amazon - and launch event partner The New York Times - pitch as more convenient for newspapers, and textbooks, than the smaller Kindle 2.

The Kindle DX  (Amazon image left) also has a super-sized price - $US489, or $US130 more than the Kindle 2 and initially will only be available in the US.

Latest rumours say Apple’s coming device is not a touch-screen netbook but an Amazon Kindle-style ebook reader.

Why should Kindle and Amazon.com enjoy all the accolades of being the iPod and iTunes of books?

New evidence points to Apple scheming for iTunes to be the, well, iTunes of books.
