> Maybe this depends on the person, but I find a device with some buttons to configure it infinitely easier and less frustrating than an app.

People's subjective experience may vary, but relying on an app objectively entails more complexity and risk exposure for the user than exposing on-device configuration.

It's quite possible that many people who say they prefer using apps do indeed experience a higher level of frustration over the full span of their usage, and are only expressing their immediate-term evaluation at the outset of usage.
