It is not meaningless, it is describing parallel (or at least comparable) revolutionary technology. Think about each you mentioned: How many industries where positively impacted by the advent of cheap pocket or desktop calculators? Would the Apollo missions have been possible (or as successful) if the astronauts had to calculate every azimuth with a slide rule? The slide deck seems focused on the point that mobile is the next major revolutionary technology, comparable to the introduction of super computers and the other revolutionary tech that you cite.

Really? You're going to dismiss the ability to pull up maps and be guided to your destination. Voice recognition, browsing the web, a music player, and having a video game console in your pocket.

Im not dismissing any of those things. Im saying the phrase has been used so much in vague contexts that it has become meaningless.

Yeah, every computer is a super computer compared to those that came before it.
