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.
