The email app that changed how you manage your inbox? It was acquired and shut down. You broke your phone and now you have to reconfigure and restore your apps and data. You keep your notes in a Japanese Midori MD notebook with grid lines… but you left it at home.
The upshot here is that when we opt for the shiny fancy tools, they're actually another way to stay busy and avoid what we really NEED to get done. If we're spending more time setting things up, or searching the app store, or looking for the right pen, you can hear the sound of hat deadline whooshing by.
My apologies to Douglas Adams for that, but in my defense I did use that in the correct context.
