Using iOS means learning how to finger dance. Press-Press-Tap-Pause-Swipe-Pull-and-Slide!<p>For a laugh, I walked into a UX lab at this year&#x27;s WWDC. I started to talk about my app in terms of GOMS - specifically Fitts law. There were two Apple UX engineers. He didn&#x27;t know what the hell I was referring to. She did - and really enjoyed exploring the tradeoffs from a user-centered-design perspective. We discussed personas. Gesture cost. And the tradeoff of breaking an idiom. I hope she gets promoted.<p>I was introduced to GOMs by Jef Raskin. He also left when Jobs came back. I wonder if there is a tradeoff between product and UX. Parc had rigorous design during its downturn. Apple had great designers during its downturn. Maybe part of the magic is hiding the rabbit under the hat.<p>And then there&#x27;s Apple Music [shaking head] geez.
