My ongoing internal debate around Android Vs iOS continues. With the Galaxy S22 Ultra looking like it's going to be a 'Note' in all but name it's becoming an attractive option. It may not be the best handwriting platform but, with the built-in S Pen and handwriting recognition, it could be interesting to explore the capabilities.
My wife previously wondered if I might be interested in the Rocket Book range – reusable notebooks. They are an intriguing idea but reviews vary of exactly how reusable they are and the friction of the extra steps to scan your writing then having to deal with a cloud storage service are off-putting.
You then have the reMarkable but that's out of my price range.
