Each to their own. I found earlier versions of Sonar on a single monitor a nightmare for the way I like to work.
I think X1 introduced the idea to many that you may need to invest in a greater vertical resolution from a monitor than was previously recognized as being an essential requirement even to see the pro-channel inspector in it's entirety.
I can work comfortably on any application with a single monitor the size of the display required to run the first of the X series.
The fact that it prompted many to look at a minimum of a vertical 1200 pixel display may have helped in the perception that a single monitor is now all that's needed where two monitors may have been required before.
A dual setup is still helpful in many scenarios. I wish I had a spare screen sometimes.
(p.s can someone explain to Mike that scoring studios have acres of screen real estate that doesn't compromise the listening environment. He seems to have wandered down yet another blind alley, bless him! Still, as long as he ends up convincing himself of something while he's here, that's all that matters.)
