I love writing things down when I brainstorm; it helps me think. But taking notes by hand is not feasible for me. My handwriting is atrocious (always has been); if I want to write a nice-looking text, I have to slow down significantly, and then it becomes too slow. Also, searching, indexing, and everything - it works better with digital.
I think iPads now have a feature that 'neatens up' your handwriting. It's supposed to retain some of the original character, but just be a bit more legible. I've not used the feature but look forward to trying it when I upgrade to a newer device.
