I am thinking about buying an E-book reader but not exactly sure which one I should get.

I was weighing the options between the:

-Kindle2

-Sony Reader Pocket Edition

I know the Kindle2 has text the speech which is one thing that interests me but I am not sure if the Sony readers have that. I have trouble finding much on the Sony ones. All the readers above seem to have the same display type (which I like). Does anyone know the support for the Sony readers as far as having free, non-copyrighted, e-books available for download (which I have read the Kindle has (or Amazon...whichever)?

Thanks
