Four years have passed since the Amazon Kindle first burst onto the scene. An addition in the long line of fancy gadgets, this device catered to a limited segment of the audience: the passionate readers. The sales of the Kindle vary from the notion that reading is losing its value as a habit. Nowadays, more eBooks are sold than physical books. This only goes to show that digital books are the way of the future. Several models of the Kindle are available in the market. Here is an overview of their features.

Screen Size
The Kindle has been following a standard 6 inch screen ever since it was launched in 2007. The screen size hasn't been increased in all the models, though some like the Kindle DX have a larger screen which makes reading easier for you. Amazon has ensured that the users' eyesight isn't adversely affected by reading on Kindle. Furthermore, the new Kindle includes a touch screen which provides you greater accessibility and ease of use while reading a book. If you want a large screen, then the Kindle DX is your only option. The rule of thumb for the other Kindle types is 6 inches.

Storage Capacity
An area where the Kindle has scored well is the storage capacity. The original Kindle only had a storage space for 200 titles but had extendable memory. Now, you are able to store up to 3GB of content on the Kindle which is enough to survive on for a while. You can create your own library on the new Kindle! Amazon has been increasing the storage capacity with every model to ensure you don't have to refrain yourself from getting new books on a daily basis.

Width
The Kindle is a slim device, making it highly portable and easy to hold. The original Kindle had a width of 0.8 inches. That was the thickest version of the Kindle so far as Amazon slashed the width by more than half for the Kindle 2, which is all of 0.36 inches thick. The thinnest version of the Kindle so far is the third generation model, which measures 0.34 inches. The slimmer the Kindle, the easier it is to use for you. Even the thicker models aren't going to be difficult to handle for you.

Weight
Along with width, the light weight of the Kindle also made it easy to carry around with you. The first two generations of Kindle weighed the same, 290 grams or 10.2 oz. Kindle 3 was lighter than them, at 8.7 oz or 247 grams. The Wi-Fi version of the Kindle 3 is the lightest of them all at 8.5 oz. If you look at width and weight combined, the Kindle 3 is the lightest and slimmest version of the series.

These are some of the key features of the Kindle. If you are an avid reader and like to have a large number of books at your disposal, then buy a Kindle now and indulge yourself! By the way, the Kindle comes in both black and white colors, so you make your choice.
