Properly done radial knobs do not force you to move the pointer in a 
little circle, but allow you to increase the distance. This way, you get 
adjustable precision. In my own experience, this can work very well for 
parameters that have a huge range (i.e. _many_ steps) and control 
something sensitive to the smallest changes.

One issue is the placement of the knob relative to the edges of the 
screen and what you do when the pointer (ignoring touch) reaches them.
