I think the primary use of quaternions in modeling 3D motion is to avoid the dreaded "gimbol lock."

I'm sure there are other practical applications of quaternions, but for ordinary electromagnetic phenomena, quaternions obfusicate an already difficult subject. Though they seem to pop up when more complicated electromagnetic phenomea are studied, like magnetohydrodynamics.

Gimbal lock is another way of describing division by zero problems. 

Nominal Animal:
If you don't like using unit quaternions (also called versors) for 3D spatial rotations, use bivectors instead.

The elementary algebraic operations you end up implementing stay exactly the same.
