I fear Apple Notes, which I use religiously. The problem is, I use it to its fullest-with long notes, PDF attachments, drawings, and so on. I’m afraid at some critical point I’ll hit some undocumented wall, and find that I’ve a usage or search limit, only to be told “you’re not supposed to use it that way.”
true, and I have some of the same fears. I figure worst case its a weekend of exporting the handwritten parts to PDF and copying the text from the rest into org mode, but with all things APPL going too far outside of mainstream usage is a real risk.
Its good if you use an iPhone, great if you use a Mac too and fantastic if you're "all in" on the apple ecosystem with a watch/ipad as well.
Organize it using a GTD like system and you'd be hard pressed to find something that is as powerful as it is while being super simple.
