First of all YES it can be done. Although I must admit you are the first person I know willing to spen the sort of money required just for cut n past to word from a web page LOL
Most users of this feature are musicians (andmost tend to use MAC, which has been capable of this for years), they use the feature and have the mixers etc on one monitor and the song score or something on the other!!
Although in the last 2 years or so, they have became very popular witht he gaming world, this has driven the prices down. 19" monitors to around £300, 17" to around £170 & 15" to around £80 (you can even buy a reasonable multi-lcd array for under £1000.
