I was spooked away from OneNote. I mistakenly deleted an entire notebook on their iOS app with a single swipe and press. Bizarrely, the notebook was completely irrecoverable. Not only that, but the desktop version of OneNote, which previously had the same notebook, automatically synced the deletion. I laughed at how efficiently I was being screwed. This was a couple years ago. I reluctantly switched back to Evernote.

I’ve also had trouble with OneDrive. I like most Microsoft software, but MS needs to rework its schema for auto-save products. They’re seamless 99% of the time, but come with the black swan risk of catastrophic failure at the worst time. I’d rather just ctrl+s and email backup copies to myself.
