@Shane, great point. Since a long time, I have been wondering about consumers and wearable devices, and how an aggregated consumer is expected to upgrade a $300 wearable device with X number of sensors and limited app availability, with another $300 wearable device with X+1 number of sensors and a marginal increase in app availability. In the workplace, these concerns a replaced with promising possibilities. For example, if APX Labs can help a telecom service technician to increase efficiency by even 5%, then $300 and subsequent, upgrades costing another $300 -- delivering another boost to efficiency, won't be too hard to justify.
This is why I feel, that wearable devices might turn out to be like the PDAs, finding their success first in the enterprise and later at the consumer end.
