That is too harsh @selinz, there is a several billion dollar industry based on GMR (giant magnetoresistance effect)...I am pretty certain you have a GMR based disk drive somewhere in your home...GMR has triggered the rise of a new field of electronics called spintronics which has been used extensively in the read heads of modern hard drives and magnetic sensors....what we are discussing here is whether you can make a logic circuit based on spintronics not whether spintronics is useful (it clearly is)...Kris
Spin devices are getting increasing attention, see for example recent emerging technologies symposium held in Vancouver last month (www.cmoset.com) and are posed to revolutionize charge based electronics we know...the key question remains when we will see these devices deployed in real world, commercial applications?

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. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
