Unless you're applying for a post-doctoral position at a corporation or somewhere else where HR personnel will be screening your materials before forwarding them to the person doing the hiring (where GPA might be scrutinized), I don't think it frankly makes much difference. Your work as a researcher matters much more than your performance in an elective course taken in graduate school that may have little to do with your proposed research area for the postdoc. 

Potential Impact of Pass/Fail vs. Letter Grade in Elective Courses
I am looking for a way to recognize handwriting of scanned notes (in PDF format).

It doesn't have to be perfect, and it doesn't have to free, but before paying I would like to try it (even with just a single page).

It doesn't necessarily have to be a native Mac OS X application. I would be OK with an online application, or a Unix application to install or compile. In other words, anything that works somewhat decently would be OK.

I am also not necessarily looking for a perfect result. Even transforming my notes into a searchable PDF with just some of the text recognized would be better than nothing.
