Well, you're much further along than myself. The first time that I learned of the book was today, when I stumbled across the Claremont review quite by accident, and thought that others might be interested in it as well. I will probably buy it, as it's available used from Amazon for only $11.
I have terrible handwriting also....I think that it can be easily confused with that of severe head trauma or mental patients :-) Thank Goodness for word processors....they make it possible for me to appear halfway coherent, although they prevent me from developing a more refined handwriting....I often look at our Founding documents and marvel at the beauty of the script, as well as the timeless beauty and truths of the words.
I haven't tried it, but one thing that you may wish to consider, if you work with a lot of handwritten notes, is a Tablet PC. You can write directly on the screen and it uses handwriting-recognition software to 'read' your handwriting and convert it to standard font lettering.
