I too have the 505 and like it and for tech pdf's haven't found a good way to format them in epub or other way yet.
Really both of us have both ways to go , learn better ways to reformat the pdf's to fit the altered pdf's for the 505 or find a good way to convert them to LRF or epub to a way that works.
If there would be a way to change the page in pdf format to fit 6 inch screens that would be great for me, it could be out already and I just don't have the info .
Anybody have a way to convert tech pdf's to epub or LRF format so diagrams,pictures, charts, etc to it works on 505?
It would be nice if adobe came out with a pdf to ereader conversion to 6 inch or 5 inch ereaders. Then the program could do the magic to make it fit on the 505.
