I voted for Spock, but only because he got the most out of my favorite character - The Computer.
The voice of Majel Barrett-Roddenberry played the most user-friendly voice activated interface ever conceived.
As a child I was in love with the idea that all of human knowledge could be stored in a machine and that your challenge was how to phrase the right question to find out what you needed to know. Spock was always teasing information out of it by asking questions over and over. I blame this for my lifelong obsession with computers. I never got over it.
(Notice: only in the parallel 'evil' universe was the "ready" prompt used, rather than the traditional "working". What does that say about the universe we live in?)
Wait! This isn't a Parachute, this is a Backpack!
