Does anyone have any experience with digital notepads? I need something that is lightweight that I can take in the field with me. It needs to be able to convert my handwritten notes into MS Word.

I've read through the various notepads on Amazon, and I think I'm more confused than ever. I like the idea of using regular notepaper as it is cheaper in the long run. I first saw these in the skymall magazine on a Delta flight, but that one doesn't go into Word. I think.
