OCR software for handwritten notes 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.
You could use Evernote for this (Free). Just import all of your PDF's as notes and after some time (you can speed this up by upgrading to a paid account), it will automatically process them and recognize the handwriting. You won't be able to extract the OCR text from the notes, but you can search for it.
