Aside from the higher throughput, one of the other great things about it compared to analogue dial-up modems was the almost instant connection speed while old analogue took tens of seconds, maybe even a minute.
But the biggest thing that really made it feel “responsive” was its digital nature, meaning that your baseline latency was mere sub-10 milliseconds instead of 150ms for analogue.
Generally our monopoly telco was despised, but they had a great offer called “R7 weekend” where from 7PM Friday to 7AM Monday, no matter how long the (domestic, possibly local, only of course) call you would never be charged more than R7 for it. This meant that you could be connected for the whole weekend at 128kbps for R14 (~1.4 USD) at the time (2003-ish).
