I think the important part here is not to focus on "supercomputer" but rather on "pocket". Imo the big thing is that you essentially have what used to be a desktop then a laptop and can carry it around in your pocket and do similar stuff with it AND it's socially accepted. Noone blinks an eye if you use your smartphone all the time. Rewind a bit and people would have blinked an eye if you had used your (bulkier) laptop all the time.
It's light and mobile yet sufficiently powerful. Locational context matters a lot more now and isn't tapped into fully.
+it's usually connected to the hive aka Internet so you essentially carry lots of information with you at all times. I'd argue that instant access to information (prices etc.) can be more enabling than pure access to the underlying computer.
+some other gizzmos like an always available camera/voice recorder/music player
