Thanks for the info on the RJ Tech Digital Picture Frame.
It just occurred to me that all picture frames could be pseudo ebook readers.
Here is how.
Adobe acrobat has a feature which allows you to save the pages of pdf files as JPG files. This would allow the picture frame to work as a kind of ebook reader. Just store each series of JPG files in a folder. Stick the folder on a flash drive, stick flash drive into picture frame. Then view the pictures in the fold of the book you want to read. Use the button controls to move from page to page.
This technique may offer advantages over converting to text file because, all pictures and formatting would remain in tact.
And for those who do not have the Adbobe acrobat software, I believe thier are some freeware versions that can also do this.
Now looking for picture frame that can run on batteries and can run several hours on a charge.
