Speak for yourself. In operations, I have far too many graphs and widgets and knick-knacks, and I can really use all the real estate given to me (particularly when in command). I have duals and still don't have enough. At my last job, I even stuck a USB dongle on my iMac for a third, but it ended up being a painful experience and negatively impacted things like Exposé.
You can never go too Star Trek when it comes to cool graphs. It's not a pissing contest, either, honest; I genuinely need all of that information in front of me in a crisis.
