This App Turns Your iPad Into a Second Monitor, by Robert Ambrogi, LawSites Blog

When you start using two monitors, many of us are hooked. My favorite feature is the ability to drag documents and websites back and forth. Imagine having a spreadsheet or other document open on one screen, and the document or source of the information you need on the other screen. If you need to keep an eye on email or your docketing calendar, you can keep it up on one screen and work using the other. (If you do not have a second monitor, you can access your other open windows using Alt-Tab.)

I can understand why Mr. Ambrogi is excited about this app. -CCE

I am so dependent on a second monitor that I no longer feel productive without one. That can be a problem when I am away from my office. It is especially a problem when I travel and am hunkered down in a hotel room with important work to get done.

Then I discovered Duet Display, the app that turns your iPad into a monitor.
