Amazon has started taking orders for the latest version of its Kindle DX, which boasts 50 percent better contrast and a lower price of US$379.
The second generation Kindle DX is US$110 cheaper than its predecessor and comes with a new graphite casing. The 9.7in e-ink screen has been improved to give clearer and sharper images when displaying books, newspapers, PDFs and magazines, said Amazon.
The online retailer will continue to supply free 3G to all users, stating that connectivity will be available in more than 100 countries.
The Kindle Store has more than 620,000 books available with prices for New York Times bestsellers and new releases starting at US$9.99. There are also 1.8 million free out-of-copyright books, downloadable in 60 seconds without the need to set up or use a PC, according to the retailer.
The updated Kindle DX comes just one month after Amazon released a Kindle App for the iPad.
The Kindle DX is scheduled to ship on 7 July through Amazon.com.
