After my family leaves in the morning, I'll make my first coffee of the day and then I head upstairs to go to work. At least, that's my plan. I'm not going to check email. I'm not going on Facebook, or sneaking a glimpse at my Instagram feed. No. I'm not going to down that road. But with multiple devices, by the time I get upstairs [to my study] I may well have heard my iPhone ding and - it's Pavlovian.
