I bought a Microsoft Surface and found it good. I had a matte protective coating put on it that made it better. About 10 years ago, I bought an Echo pen, which was really good! I would write with this pen into their special notebooks. As I reviewed my notes, I could touch an area of my handwriting and get audio playback synchronized to that particular point! It automatically made a PDF of my note-page! 10 years later, their technology has got to be much better! The best solution i have found is old fashioned paper and pen augment with a audio recording. nine times out of ten, I never go back to my audio recording. if I make digital text notes, I will transcribe my chicken scratch. If it's a lot of notes, I use Dragon Naturally speaking to expedite this process.
