Hello Everyone,
So I am going to receive my first eReader soon

I have lots of PDF ebooks that I would like to read on the PPro.
From what I have read I believe I can change PDF into other formats that the PPro can handle better?
I have all sorts of PDF from ones with nearly text only to photography ones with lots of pictures. I am only planning to read those with little photos and mostly texts.
Now the question is what format should I convert those PDF into and with what program?
Thank you all!
