It's the type that control multi displays a once, like at the stock market, Best Buy, TV stations, Museums and the likes. To the common pc user, yes its way too pricey. We have several of those type at work and I laugh at how much they pay just to have the multi-displays when really they dont need them. Several of our machine vendors sell us parts we dont really need, but when presented to the engineers, the engineers get ga ga and have the purchase department buy the un-needed stuff anyway!
