> muscle memory makes for very easy pickup of intuitive gestures;
The problem with muscle memory is that the gestures vary between operating systems or even different devices on the same OS if the user has changed settings. Your muscle memory ends up getting in the way instead of helping and causes endless confusion.
I dont think this is a valid argument: muscle memory is extremely contextual. Your muscle memory for your phone is definitely different from your laptop, and I don’t think the context switch is actually a hindrance.
This would extend to different devices that don’t share the same hardware (at the tactile/interaction level)
