This developer blog is an introduction to the 2701 device. It starts with a short introduction about 28 days of experience, the sensors and the technology behind it. Then shares data about how the device transforms your daily routine, from ranging to sleeping, from creating organized time lists to a visual timeline of your activities. Then shares the stories behind this device, including one from a 30-something homeowner who used it to watch his daughter while they made dinner or to schedule jobs or movies that took longer than usual in order to come home on time at the end of the day.
