Anyone who owns or is considering buying a Kindle 2 has no doubt heard of the recent launch of the Kindle DX. If you are the former, this could be a great time to upgrade and if you are the latter, it could be a tough decision you have to make. When you are looking to spend the kind of money the Kindle costs, you don't want to leap without looking. But if you do your research beforehand, you can be assured you will get the model that works best for you. And this Kindle DX Review should get you started nicely.

The older of the two models, the Kindle 2, offers a few less features and is a bit smaller, but also comes with a smaller price tag. The Kindle 2 is 8" x 5.3" x 0.36" and has a 6" diagonal screen. It weighs just over half a pound at 10.2 ounces and is great as a highly handheld ebook reader. The Kindle 2 comes with 2 GB of memory, which can hold around 1,500 books, more than enough to fit most people's libraries inside. At around 259 dollars it is a lot cheaper than the new DX as well.

The new Kindle DX comes onto the market with a bigger is better attitude. The unit itself is 10.4" x 7.2" x 0.38", but it boasts a huge 9.7" screen with an  auto-rotating feature. This means you can switch between landscape and portrait just by turning the device, making it great for newspapers or picture-heavy  kid's books. But this size means it weighs more as well. Nearly twice as much at a hefty 18.9 ounces.

The Kindle DX has twice the capacity to hold books, boasting of a 4GB hard drive. It can also natively read PDF files which is a huge convenience as the previous models required file conversion. All these features are available at the price of 489 dollars.

Don't think that just because the Kindle DX is newer and sports bigger numbers that it is the only one you should consider. The Kindle 2 has size to its  advantage. While the DX might be great for reading at home, the Kindle 2 is far more portable. It will also save you a big chunk of change. If you are willing to pay for the extra size and features, the DX is a great piece of technology. But the Kindle 2 still has more than enough to offer most people. If  you are just looking for a way to replace ratty old books or cut down on how many textbooks you're hauling around, the Kindle 2 has a lot to offer. Whichever  one you decide is right for you, you're getting a device that will give you the ultimate reading pleasure.
