Kindle DX Goes Global

Amazon (s AMZN) today announced that it will start selling a global wireless version of Kindle DX (the 9.7-inch display version) in more than 100 countries for about $489 a pop starting Jan. 19. Just like the Kindle global edition, Amazon is using GSM technologies — GPRS, EDGE and 3G — to power its global WhisperNet, which allows you to download books for free.

It’s a smart move, especially for those of us who travel internationally a lot and sometimes want to buy a book on the spur of the moment. What do you guys think? Time for me to upgrade from my first edition Kindle?
