64    Experiments[rosenb (and intuition) indicate that adjusting a physical
65    slider is much easier than adjusting a virtual slider on the
66    screen with a mouse. Despite this, virtual sliders or scrollbars
67    are far more common with computers than physical sliders,
68    probably due to economics. Adding a new virtual slider to a program
69    costs next to nothing, while adding a new physical slider for
70    each user amounts to a considerable sum of money.
71    
72    Still, complicated devices such as computer mice and joysticks
73    can be cheap due to commodity economics; the cost of user
74    interface devices has little to do with manufacturing and
75    much more to do with the number produced, as the development
76    costs are amortized over the whole production.
77    Thus, computer mice cost approximately $10-$30, joysticks
78    some more, steering wheels even more, and specialized
79    input devices such as Monkey Bones 2 REF can cost up to $22,000.
