Laptop/Ultrabook comparison with Tablets seems like an apple-orange comparison to me. They make sense in their own unique way and one may not be a replacement for the other.
I am curious if iPad has cannibalized Apple's laptop business.
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.
