Eliminating the goose-neck displays, in retrospect, was probably a mistake. While I am
approaching this from a 21st century POV, the helm, navigation, and captain's chair really need some kind of graphic display available to them to make certain they're doing what they think they are when they manipulate their controls. This may not have been a consideration in early computing, but we know better now. At least Sulu did eventually get that tactical display to help with his steering and fire control.
