> _You’ll notice with the product that we integrated a volume wheel that has what I call interaction gravity […] That is what pulls people into the product to interact with it._
> Unlike, say, the keyboard and the screen. Or perhaps they have ‘interaction gravity’ too. Man, my pen, which I just used to scribble a note, also has interaction gravity! As does the notepad! And my desk! And my chair! INTERACTION GRAVITY IS EVERYWHERE!
I also nearly choked on my drink at “I have engaged you, notebook! Show me your next level of design!”.
