Down side? Potential production problems of any new technology, conflicts with HP Labs' IP, HP-Hynix have already announced plans for a production device in 2013.
As for the technology itself, maybe there isn't one, at least as compared to flash.
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.
