Beyond Consumption vs Creation by Fraser Speirs:

“I’d like to propose that we can look at the ‘sweet spot’ for each type of device along two axes: task complexity and task duration. Task duration is the more obvious of the two: how long of a continuous period will you be using your device for the task.

Task complexity requires a little more unpacking.”

Speirs’ piece makes great reading for thinking about how to understand a wearable’s value. His visualization of how phones, tablets, and traditional PCs get chosen for different user tasks is also spot on.
