Because it's Eizo's professional Color Edge line, they are extremely expensive and meant for people who need absolute colour accuracy. Printers come to mind. I don't know if this particular model is overpriced though, because I can't find it on Eizo's website, but the CG243W is alot cheaper here, atleast. They also have one that's... ALOT costlier: http://www.eizo.se/default.aspx?page=11&product=CG232WK
102k NOK... that's around $18000
I own an Eizo myself, but it's of the cheaper FlexScan line. Think it was around $1800 when I bought it.
