While Amazon Kindle is not yet  compatible with the open ePub eBook format which gives Sony Ebook readers access to the entire Google Ebook Publick library, this library is mainly composed of public domain classics such as Jules Verne, Jane Austin and Mark Twain’s books.

But the key here is that these are public domain books which are equally available for Amazon Kindle users through the Amazon store. The problem is that Amazon seems to make it hard for Kindle users to find these books.

Here is a list of the cheapest Ebooks you can find on Amazon:

• Public Domain Books
• Free Kindle Ebooks
• Kindle Ebooks up to $3
• Kindle Ebooks up to $4
• Kindle Ebooks up to $8
• Kindle Ebooks up to $14
• Kindle Ebooks Bestsellers

Still the fact that you can get books through Amazon’s Whispernet gives the Amazon Kindle the advantage over it’s inmediate competitors, such as :

• • Sony Digital Reader Touch Edition – Black (PRS600BC) $290
  • Sony PRS-505 Portable Digital e-Reader System (Silver) $266
  • Bookeen Cybook Opus – eBook reader 400 MHz – RAM: 32 MB 1 GB – monochrome 5 $250
  • Libre eBook Reader Pro. (Black) $177
  • Sony Digital Reader Pocket Edition – Silver (PRS300SC) $195
