Regarding analog gauges, many believe people glean information from them more quickly than a flashing number that the brain must interpret using slower acting language center (as opposed to motion and position which are faster acting brain functions). If you are referring to the iTunes-like cover-flow capability, then it is definitely the "cool factor" that is the draw :)
While it may be more efficient for the machine, Humans were designed for an analog world. Humans read analog gauges far faster than they can read a digital readout. This is important when travelling at 88 feet per second down a backroad.
It's the reason race cars used to turn their gauges so normal operation pointed straight up.
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.
