All else being equal, it's better to be a quick typist, no doubt. But I've been around programmers who can type as fast as they think, and that can lead to a sort of stream-of-consciousness style that literally leaves them (and their teammates) buried in their own code. There's something to be said for thoughtful pauses while coding, time to consider the approach you're about to take to that class or that algorithm. As the saying goes, sometimes you have to slow down to speed up.
