I'm sure the motors may be used for other things as well, albeit not as
easily as separate motors.

But in a program you will always know which way the motors drive, right?
So one can possibly maintain a second variable for each motor that is
updated every time the motor changes direction. That way, it may be
possible to keep track of the distance travelled.

This sounds useful enough for me.
The speed and torque of the motors also appeal to me. The new 9V geared
motor almost always needs to be geared down anyway, so it's a good thing
that the Cybermaster motors have a somewhat slower pace. (I still
haven't used them that much, though, but that's mostly due to the fact
that I don't have a computer at home.)
