The webpage in question was with respect to win2k, i.e. their
"workstation/server" OS. Presumably win2k is running multiple tasks,
with large disk caches, etc. Still, Microsoft themselves is claiming
that disk fragmentation is an issue.
Why would they claim that it was a problem (thus putting themselves in a
bad light) unless they had done the tests to show it?

We're talking about Windows. The vast majority of installs are single-user.
