> The thing I always think about: how fast it is to play an MP3 from "device in pocket" state with an MP3 player vs a computer (or my phone!). iOS affordances around that are good. This is a very important metric! Jeff Hawkins famously walked around with a piece of wood in his pocket the planned size of the Palm Pilot, and when he wanted to do something (write down a note) he would work through how many key presses it would take on the new device. His limit was three. When I tried a BlackBerry I was infuriated by how many key presses everything took. What a horrible experience. > Having said that... maybe there's a new shell that MacOS could use to get there Like it or not, Apple’s plan for this remains Siri.
