In episode 467 of HBR Ideacast Evernote CEO Phil Libin discusses how the increasingly personal devices such as the phone or smart watch are changing how work gets done.  He makes many interesting points in this podcast, but one that stood out was how these new devices are reducing the session length of each interaction.  Where time spent on a computer can be often measured in hours, time spent on each interaction with a smart watch can be measured in seconds.   This difference, a drastic reduction in session length while at the same time dramatically increasing the number of sessions per day, means that software design must take this into account by designing not for the device but the human.  

Already in the consumer space users are requiring software that seamlessly operates from device to device depending on the context (such as Apple’s continuity).  Enterprise software, or business process within business, hasn’t caught up with this phenomena.
