> Does every single screen need to have 60 fps animations, with activities that launch from where my finger touches the screen? Does fidelity matter on an admin screen?

But this is the exact "myth" you claimed to "debunk". This is why people claim WebViews suck.

If you want to trade user experience away to reduce development work, that's fine. Lots of people make that compromise. But your claiming this is a "myth", and then admitting it's true.

Users may not always articulate this fully, but users do notice when apps are "janky" -- when animations aren't fluid, or when UI doesn't accurately respond directly to their input, or when screens "flash funny" because your switching between native activities and webviews.

You may not care about the experience that has been lost. And perhaps your particular customers don't mind that loss of care for the details. That's not inherently bad in any way. But it's not a "myth" either, you have lost a part of the experience you could have offered.
