It will take a holistic understanding of hardware, software and the user. Time will tell if the Apple model of making their chips in-house is the best strategy.

While I do worry about privacy issues (do I really want to be known where I am?), I like foursquqre CEO's comment about making "people passively aware of what's going on around them." That may be useful.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
