And bandwidth still changes everything. The thing that made browsers
fun was that the latency was tolerable, and that was only true because
the network performance was good enough that imagery was feasible to
move over the net. It's no surprise that new technologies such as the
WWW and browsers came from places that had interaction with the Gigabit
Testbed program, such as NCSA and CERN.
