Uhm, dials...

The only dial that I've ever found useful was the "real" one in the 
"dials and button box" ;).

But maybe things change with a pen..

I've used one of those. Great for data entry for 2d models, but for 
normal usage they take too much space on the table. I suspect this is 
alleviated if you take one of those with the _actual_ lcd beneath it 
(awesome), but then again I doubt this is really "comfy" to use while 
sitting.

When I need to do some UI for myself, I use a mouse on one hand and a 
half keyboard on the other (a _completely_ split keyboard, whose end I 
strapped to the armchair). This essentially makes for a "60" button 
mouse, while almost never using the mouse buttons. I've gone as far as 
using only a subset of the keys, namely the home row and the row above 
it, and use chording instead. I tried to minimize pointer precision 
requirements to be able to use a trackpad (so that I could strap it to 
the other armchair), but so far with no great success. Very small 
movements suck with a trackball, and long ones tend to be imprecise due 
to the necessity of "rolling" the ball.
