Very interesting indeed.
@UniquelyMe: Even if one has to replace the entire PCB, to the majority of consumers a faulty component usually means the whole device needs to be replaced. In that case it probably won't make a difference for certain devices or companies.
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.
