Apple Watch has now been launched. I’ve had mine for two months, and it’s making a difference to the way I work and live. The activity app prompts me to stand rather than sit, to walk up escalators, to watch the calories. There is visibility of what is coming up on the calendar, so less stress of missing something. The weather app means that I can prepare better and not get caught out. And of course I can just wave the Watch at the scanner in Starbucks to get my coffee – now decaf.
