The original claim used (without definition) the word "dominant".
I proposed (without objection so far) the definition "90% of
desktops".  My counter-claim is that Ethernet was dominant (90%
of desktops) without the arrival of switches having been the
cause.  The existence of a small number of 10-megabit switches
doesn't force acceptance of one causal claim over the other.

So how about this update: "Ethernet was serving 90% of desktops
before 50% of those desktops were talking to switches"?
