I have a 505 now, but I did have a look at the new readers in the sony store, I don't like you said have any use for a touch screen /make notes or such. I just wanted it for a reader . Considering the pricing and size I would still go for the 505, it has it all ,very clean look ,easy to use, feels good in the hand, can use sd cards and trust me it dosen't take that long to accumulate hundreds of books especially when there are so many great ones here on this site for free. But which ever one you purchase I'm sure its going to be the right one for you. Happy reading
