Eventually solid state will likely replace most spinning media. The amount of time between now and then depends on a number of factors, including cost curve, reliability, and density.
I do like that Apple took the chips out of the archaic HD module. In the near term, I can understand the value in making SSDs emulate spinning hard disks, but long-term, it seems pretty silly to force chip memory to emulate a form factor and interface that was developed with spinning media in mind. It's time to create a new interface standard specifically designed around the strengths and weaknesses of solid state mass storage.
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.
