> Trying hard not to be anecdotal, but I can't think of anybody I know that uses a note taking app that enjoys taking notes on a mobile device.
And having this view is OK and valid. On the other hand, I tend to use Evernote a lot on my mobile device, mostly in read-only mode.
I keep a lot of technical documents and cheat sheets I've written and sometimes need them while only having my mobile device with me, and it saves a lot of time.
I also scan hand-written notes for later digitizing them, and Evernote OCRs them at the background, saving me time in the process.
It's definitely a horses for courses issue, and if Obsidian works for you, go ahead, use it with its full potential.
