Hey Frenchie,
Thanks for stepping up to provide an answer, unfortunately I think you misunderstood the question. A Sony Reader is a standalone device designed for reading ebooks. It is not a Windows computer so none of the solutions that you mentioned will run on it. As far as I know, it runs only OEM software.
The Sony Reader competes with the Amazon Kindle but it can use more formats far more easily than the Kindle. The Kindle's advantage is that you can download books from Amazon wirelessly from almost anywhere that has WiFi.
There are also a couple of other products out there but they are much less common and several of them are an order of magnitude more expensive than either the Sony Reader or the Kindle.
So my question is still outstanding. Has anyone tried photoreading with these types of ebook readers?
It seems like it would be a natural fit for photoreaders because the devices are about the size of a paperback book, they have a special screen that reads more like printed type than a computer monitor (i.e., they are much easier on the eyes), and they can carry hundreds of books at a time (depending on how much memory you have.)
Thanks in advance,
Michael
