Agreed 100%. My core workflow is "snap a picture, draw on it." I deal with hardware, and the bandwidth with which this lets me get physical information into the computer is so far beyond any Markdown-based workflow that I can't go back. I suspect this result would hold for many non-software professions.

For now, I've settled on GoodNotes because it's good enough at PDF Backup, OCR Search, and drawing. I have given solid tries to Evernote, ZoomNotes, Concepts, and Notion, and they each are amazingly better than GoodNotes in at least one major respect, sometimes multiple, but none of them are good enough on those zero-compromise requirements and GoodNotes is. FWIW.

EDIT: Oh, while I'm flamebaiting, I also use my ipad camera to take pictures of screens. Life is too short to schlep screenshots between computers, especially the ancient ones that run scientific equipment (lots of 68000, XP on some recent ones). Printer emulators and java applets can get bent. Runs everywhere, my ass. Moore's Law has given us gigahertz and megapixels, and if I can use them to eliminate painful asinine pointless busywork that's my god-given right and nobody is going to convince me otherwise. Sometimes I even use my ipad camera to take a screenshot of something on my PC and toss it into the mix. Sue me.
