Starting with the construction, it is pretty obvious that the two are quite similar. However, despite the display that has the same dimensions, the Sony reader is smaller and weighs less compared to the Kindle 2, meaning that is easier to carry around. In addition, we reckon that the Sony also looks much better.

When it comes to comparing the displays, we have to start by telling you that they are the same size and both are very good. Reading a book or a newspaper becomes a pleasure for your eyes because of the electronic ink technology. However, the Kindle 2 has a better contrast which can be helpful in many situations. On the other hand, the touch screen display that comes with the Sony reader is a brilliant addition that has to be taken in to consideration.

Because we compare two ebook readers, we also need to talk about the books. Here is where the Amazon product gains advantage. The impressive WhisperNet and the fact that books can be downloaded in less than a minute are of great importance.

When it comes to battery life, things are pretty similar, both provide about two weeks of continuous use which is more than enough if you would ask us.

The Kindle 2 comes with 2 GB of internal memory, but with no card slot, while the Sony Reader Touch has only 512 MB of internal memory, but it can be upgraded up to 16 GB by using a card.

Finally, the Amazon Kindle 2 comes with a smaller price of just 259 US dollars, which is a great deal judging after its internet capabilities. On the other hand, the Sony Reader Touch costs 299 US dollars but provides an interesting touch screen.

We decided to stop and take a look at the Sony Reader Touch Edition or the PRS-600 as it is better known. The main weapon of the PRS-600 in its battle with the rest of the competitors is the 6 inches touch display with 8 levels grayscale and 800x600 pixels resolution that is extremely easy to use and provides a great reading experience. This model is also comfortable to use and carry around because it is only 0.4 inches thin and weighs around 10 ounces. In our tests, performance proved to be very good, without any problems in page turning and scrolling. While some readers have problems when it comes to battery, Sony has fitted one that lasts even for two weeks of continuous reading, which in our opinion is exceptional.

The internal memory is limited to just 512 MB, but this should not represent a problem because it can be increased with the help of memory card slots that support both SD cards and Memory Stick Pro Duo. The price is also great in our opinion, at just around 299 US dollars, more than reasonable for a qualitative and easy to use reader like this one. 

When it was launched, the Amazon Kindle 2 was priced at $359, but as the Kindle DX was released, the price continued to drop and you can now purchase one at a great price of only $259. And in case you are not from the United States, be advised that an international version of the Kindle 2 was launched in October 2009.
