Probably not a good solution for converting PDF where math formulas will look good. I wrote a math book for radio communications and the only good way I found to get the formulas to look right was to put them in image files. It was a tedious process where I used MS Word to create the formulas then took screen captures and resized them to fit the 600 x 800 E Ink screen. Unfortunately mobi does not support a math markup language.
