>Depends on the pov. Is it better to have a system that is over-used (because it's free) or one who is under-used (because too expensive)? In the first case, you may have to wait to get your treatment, but you will receive it eventually. In the second case, you may never receive it.

But when/if you do, you can be fully assured that the equipment's idle time is calculated into your price... plus some for the future equipment that will keep us ahead of the competition (which will have the same equipment, also underused and therefore overcharged).
