I have an ipad M4 13” nano, a kindle paperwhite, a Scribe and an ipad mini. My favorite device is my M4 nano. I use Apple notes every single day. I use Apple Notes as my bullet journal, my diary, my commonplace book and any other note that I need to write, or document I may need to capture. I always have my iPhone with me, and more likely than not a Ipad as well, so all my information is at my fingertips. Plus with the Kindle or the Books app, all my books as well. My most treasured, and most used device is my M4 nano 13. Actually I am thinking of trading in my mini for an m4 11 nano, just because the mini is jsut a wee bit small to read on without enlarging the text, and the lack of Promotion messes with my eyes as well.
