The high end of vienna is actually more:
Vienna Symphonic Library Vienna Instruments Symphonic Cube Extended Library | Sweetwater.com
Not really a fair comparison because I'm sure the Vienna library includes a lot more content, but if you compare it to what libraries and the hardware to play them cost in the samplecell days it doesn't look as bad.
I did one more calculation for DVZ, that was buying the components for the two PC's seperately and building them yourself. It came out to about $750-$800 per machine, which would bring the total price down to around $4000. Of course someone who builds and resells PC's also somehow manages to be about the same price. The markup on those parts must be insane.
