I have toyed with the idea of written vs. digital notes for some time. I recently had the chance to acquire a new generation tablet PC (the Lenovo x61) and I'm liking it for daily use. The x61 is a convertible tablet, so I have the flexibility of a traditional notebook computer, or I can spin it around into slate mode for inking with the pen. The inking has improved greatly over the years (my first attempt was with the first generation hp tablet - tc1000 I believe) and feels just like pen on paper.
I am experimenting with Microsoft One Note on the tablet - it seems helpful to be able to search my notes (no need to convert to typed text unless you really have a preference) and have my reference files with me at all times. The tablet is a thin form-factor and not a hassle to carry. The newer tablets have better battery life as well. Worth a try if you have the resources.
