well, i'm not going to say they came up with the best design they could have but i've had mine about a year and after a little time getting used to it and finding a cup that works well, i'm happy with it.
i think there are several design matters, ergonomically, where you have to adapt to the car 'cause it sure ain't gunna adapt to you.
cruise control, window switches, cup holder.
i guess it's part of the charm.
