I like that Apple Notes gives me the option to write, easily add images, make tables, etc. While 98% of my notes are just text, and some of these things can be done in markdown, it is higher friction in markdown. So I’m choosing the lower daily friction and extra features, knowing that I’ll probably experience one high friction migration day in the future, but that day could be 10 years from now.
The biggest issue moving notes out of Apple Notes was the extra new lines and spaces all over the place. I have to assume if the app is going to shutdown that some nice developer will make a little tool to take care of this. If not, meh… I’ll use it as an opportunity to clean up some clutter.
