Saving handwritten notes for future reference
It's not an answer, but it's too long for a comment…

I have one word for you in the future: Moleskine. Good quality notebooks, organized either thematically or chronologically, is a great way to store that sort of information. For notes, long term conservation is a big issue, and you have little guarantee that bells-and-whistles software X will still be working on your computer in 10 to 20 years. Simple solutions (both electronic and not) are the best for that purpose. 

Finally, I have managed my notes electronically for some time (I tried many combinations, including iPad/Evernote/Dropbox, text files, LaTeX), but wasn't satisfied for the reasons above. I went back to dead wood storage (aka paper) with delight!
