It’s not a smartphone and it doesn’t run Windows Mobile, but Amazon’s new Kindle 2 wireless ebook reader has our attention; and it’s worth yours, too, if you’re a voracious reader.

The Kindle 2 has an improved E-Ink electronic paper display, more internal memory, better battery life and a new slimmed-down design.  Amazon has also increased the number of converted Kindle books to over 240,000.

Books and newspapers are downloaded over Sprint’s wireless network, the price of which is included in the book purchase price.  Want to read a book on the Kindle? Just purchase the title and have the complete text within a minute, without connecting to a PC.  

Unfortunately, the Kindle 2 has some downsides.  First, Amazon has removed the SD expansion card, although the reader does include more internal memory storage.  Also, the price decrease that many expected didn’t come – the Kindle 2 is still $359.

The new Kindle 2 reader is now shipping from Amazon.  We’ll post a review soon.
