Seems like a humble choice for an executive to not take <firstname>@corp.com.
I was under the impression that Steve Jobs’ was sjobs@apple.com
"steve" was a collision from the start.
I could imagine Steve Wozniak offering to use surnames only as a joke - because that wouldn't work either.
It would probably work better for the two Steves than it would for many others.
According to the below random site, there 218 Jobs and 10,602 Wozniaks. It claims 410,801 Steves.
