Have been working with dual monitors for about a year now. Its one of those things I wouldn't do without now. Huge productivity benefits once I resited the hurge to use Alt+Tab to switch between screens!. I didn't even realise the graphics card in my PC had this capability until my wife wandered into my workshop one day and hooked it up.

Yes look like a geek, and a visiting engineer reckoned I was working in the star ship enterprise. Love It! =:)
