I just bought a 2007 ford tarus and noticed the rpm gage doesn't move at all, is that a good thing?

Tachometer is either broken and not hooked up - not any worse than a broken radio.

Since your Taurus is an automatic an inoperative tachometer isn't an issue at all. As CB said, its either broken or someone has disconnected it. It makes no difference in the serviceability of the car.
