@Peter Clarke: some how the numbers you cite above and the ones by iSuppli don't correlate. For instance, iSuppli is forecasting MEMS growth in consumer & mobile opportunity at ~$4.5B by 2015. If you take out mobile & tablets, there is $3B opportunity in the 'consumer' products? I wonder what are these consumer products that are poised to grow so much with MEMS in them... I know auto's use many sensors but not all of them are MEMS-technology based.
@Peter Clarke: see also my comments under your colleague's article on the same topic:
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.
