Dr. Drang, with exactly what I was thinking all day long:
Here’s a thought experiment: Imagine a new note-taking app written by an unknown developer. It’s has a nice, clean look and is easy to use, but it has no syncing, no TextExpander support, and no URL scheme. Assuming the app got any attention at all, how much effort would Apple bloggers put into defending that design choice? How often would the phrase “data silo” be used?
Personally, I’ll take Notes.app’s ugly UI over Vesper’s flat (and in this writer’s opinion, bland) UI every day because it is on all my devices and it syncs like magic.
