What do you mean by "animated cockpits"?
If you are referring the the gauges, than those are useful throughout the flight.
Rudder pedals, throttle, 'joystick', flap switch (ie:spitfire), seeing your ailerons roll,
your rudder move, your elevators move.
Heck, we don't need our wheels to move yet they do. Some planes you can't even
see the flaps when they're deployed, yet we have that.
Though I don't always agree with 'pig', he's got a point. It's all about the eye-candy,
immersion factor, and fun.
