Yeah, and that may be part of the problem. When you hold a single object in both your hands, your body becomes kind of unified. If you're holding two separate things (even if tethered), your body becomes bicameral again. At least mine does.

When you're driving down the highway, do you keep both hands on the steering wheel or one on the wheel and one on the gearshift? Why?

Regardless, a gyroscopic mouse doesn't require that the controller be split like that.

I bet money that there will be companies that are going to release products that will be adapters to hold both parts in one unit.
