While some companies are eager to get their e-readers out in the open, others are experiencing inventory shortages because of high demand, and Amazon was just forced to delay the shipping date of the third-generation Kindle to September 17, as opposed to September 4 as was originally intended.

Not long ago, Amazon set up a new batch of Kindle e-readers for pre-order, but it seems like the company won't be able to stick to its shipping schedule.

Because of strong demand, the product was sold out quite fast, forcing Amazon to push back the date of availability to September 4.

Now, that shipment date has slipped again, to September 17, hinting at the fact that demand for e-book reading devices may, in fact, be higher than one would guess.

This delay applies not only to the version with WiFi wireless connectivity, but also to the one with WiFi and 3G, though previous orders will still be delivered on time.

Their main asset, over their predecessors, is the new Pearl screen from E Ink, which has 50% better contrast that the display used in earlier units.

The screen also has a decent measure of sunlight readability and darker fonts, even as the device itself has a 21% smaller body.

The third-generation Kindle is also 17% lighter (8.5 ounces) and has double the storage space (Up to 3,500 Books).

What's more, it features 20% faster page turns and a battery that, with the WiFi off, can keep the electronic running for up to an entire month.

Finally, Amazon threw in an enhanced PDF reader, with highlights and dictionary lookup notes, and an experimental WebKit-Based Internet Browser.

End-users interested in the full rundown of the specifications need only stop by the official product page set up on the official website. Those willing to pre-order will be able to do so through this page, so long as they are willing to part with $139.

UPDATE:

As a clarrification, orders placed prior to the pushing back of the shipment date will be delivered on time.
