Sony adds over half a million books to Reader devices through Google

Here is the text of the email I received concerning the Google books optimized for the Sony Reader platform:
Dear Fellow Reader,
We are happy to announce a new addition to The eBook Store from Sony. Starting this week you can access more than half a million free public domain books from Google optimized for current models of the Reader*. Click on the Google banner on the home page to search for books that you can preview and transfer to your PRS-505 or PRS-700 at no cost.
The current Reader Digital Book by Sony presents an open platform which makes it easy to access a wide variety of content — whether that content is purchased, borrowed from a library, or free. We will continue to provide premium content through our eBook Store and we hope you will enjoy this added benefit from Google.
Thank you,
The eBook Store Team
Does this availability change anyone's opinion about whether or not they are going to buy a Kindle 2?
