Together with the Kindle Fire tablet Amazon announced today a plethora of new Kindle eReaders that are worth your attention. The three new devices are Kindle, Kindle Touch and Kindle Touch 3G. The previous Kindle generation was renamed to Amazon Kindle Keyboard (WiFi and 3G models from &99 to $189) to denote the presence of a physical keyboard that lacks on the new Kindle eReader.
Let’s digg in and see which one is appropriate for you as features and pricing are concerned. Prices vary from $79 to $189 so there’s quite a range to choose from.
The New Kindle is meant to replace the old Kindle reader, the one with a keyboard at the bottom. By ditching that for a on-screen version we get a 30% lighter eReader with an 18% smaller body. The same 6 inch eInk display was used for the new Kindle. 2GB of internal storage can keep up to 1400 books, but no worries as everything you buy is stored in the Amazon Cloud service for free. You can download/add/remove items on your device and they’ll still be kept on the cloud.

What makes the new Kindle more appealing is the fact it costs only $79 with Special Offers (ads that are appear from time to time) or $109 without the Special Offers. It’s an evolution, not a revolution, as you can expect. It’s WiFi only, so no 3G this time.

Now we’re stepping up to the more advanced Kindle Touch, a first for Amazon’s eReader line-up. As the name suggest it’s a touch screen model. It’s support multi touch through the Infrared technology on top of the award winning eInk 6 inch panel. It’s 8% lighter and 11% smaller than the previous Kindle. Thanks to its 4GB of internal storage up to 3000 books can be stored on the device, with all content purchased available in the Amazon Cloud Storage service. Whisperync will keep your bookmarks saved so you can resume reading on another device. All Kindles have that and all non-Amazon devices with the Kindle app installed.

Battery life is two months long, so you won’t need to recharge more than a few times a year, despite the new touchscreen. The new X-Ray function searches through through the book for ideas, characters and more and then displays detailed Wikipedia and Shelfari descriptions. It’s a lot of content on the side that will help you better understand historic books for example, offering info about what’s being depicted in the book.

The introduction of a touchscreen allows you to tap three zones of the screen which will then perform the Next Page, Previous Page and Menu actions. That’s clever and very simple to use at the same time. Personally this is the Kindle I would buy. It’s only $99 with Special Offers and $139 without.
This is nothing more than a Kindle Touch with HSPDA modem (fallback to EDGE/GPRS) which connects through AT&T in US and other Amazon partners outside US. As with previous 3G Kindles you don’t need any kind of contract, as 3G data costs are included in the materials you download. I costs $149 with Special Offers and $189 without. It’s a little bit more pricier than the normal Kindle Touch, but it’s recommended for complete freedom.

I've always said tablets need to be cheaper, something like 200-300$ maximum, to become mainstream. Now Amazon is proving it...
