Well, now we know why Amazon's stock of Kindle 2 e-readers evaporated so quickly. Just hours after I wrote about the devices being out of stock, Amazon announced a new model of its popular e-reader. The device, called simply the Kindle, is available for pre-order now and will ship August 27. While most of us will have to wait a month to get our hands on the new gadget, a few lucky bloggers and technology reporters already got a chance to check it out. So far, they seem to like it...a lot. In fact, in reading many of the reports about the new Kindle, I found it difficult to find anything they didn't like about it.
