I have strong opinions, but Ken "Mr. Two Hands" Hinckley sums them up fairly
well.

My sole additional comment would be that you have to be careful not to just
"throw 2 hands at the problem".  I've played with some interaction
techniques this summer for simultaneously manipulating the camera viewpoint
and an object of interest, and in some cases the techniques work better
using 2 hands and in others they work better if you interleave the tasks so
that they are performed using one hand.
