Review of the Kindle Fire HDX - WSJ.com

Excerpt from a Walt Mossberg review

"I've been testing the Fire HDX, and it's a good, basic color tablet. This latest model, which starts at $229 for the 7-inch-screen version I used, is a definite improvement on last year's Fire HD, which started at $199 for the 7-inch version. (There's also a costlier, larger HDX version, with an 8.9-inch screen.)
Like earlier Fire models, it's best thought of as a hardware gateway to buying digital content from Amazon. The base model blasts ads at you from the home screen, but you can buy one without ads for $15 more."
