even massimo vignelli needs a power cord
But unless Vignelli has an intern whose full time job is to quick (!) plug in the master's laptop anytime he's not looking to make sure the master's MacBook never runs out of power, then his desk most likely looks something like this.
Update: Walt Dickinson recommends that the master drill a hole in his desk in order to minimize how much cord lays there. The more I think about it, though, the more I'm of the opinion that he has a power supply intern, full time.
