While I rarely switch my phone off, (i.e. never) I do like to make it shut up when I’m busy. That means that I had to adjust all my push notifications, because I don’t want an update whenever you like a cat on Facebook.
When I have people over dinner, nothing annoys me more than a friend who keeps checking his email, Facebook updates, Twitter feed, etc. on their smartphone. It’s time to end the annoyance by purchasing the latest signal jammer from Chinavasion.
