Except in some specific cases (like when your job is to regularly download and upload huge files) latency is even more important than bandwidth. Even fairly low bandwidth under 10 Mbps is enough for the majority of real-life office job cases and it feels this way if the latency and jitter are low yet high latency/jitter can make even a 100+ Mbps connection unbearable. It's low latency that makes Internet feel fast. ISPs should advertise latency and jitter levels alongside bandwidth and that's the most important numbers customers should look at.

I usually explain this to non-techies by inviting them to imagine they own a train full of 1TB drives. This way they can move a million terabytes to a neighbor town in an hour. Naïvely this translates to 277.8 Tbps which seems super fast but there is a catch :-)
