I'm an SVP at a music company, running our Emerging Technology group. It means I'm half CTO and half business development. What Hardware I use: Work Primary: - Mac Pro, 8 core, 3.03 ghz with 16 gigs of RAM. 4 TB of hard drive space, and dual Nvidia something or others. This drives two Dell U2711 27" displays and 2 23" Samsungs with those ultra high res PPI. Hooked to this machine I have an external BluRay, Drobo Elit…

I use the left screen for iTunes, Pivotal Tracker and a VNC console to a screen of "tops" running on all our servers. We call it the War Games Console.
Left screen is email and "communications/information" including NetNewsWire, some other feeds, etc.
Middle right is my primary display for browsers and coding.
Far right is where I keep rememberthemilk.com, Gabble (a Yammer client), Echofon (twitter client) and IM/Skype.
On my Ipad I usually have SkyGrid running, which is a realtime news client. My laptop on the left is just so I have it available.
The other thing about my home setup is the MacMini server controls our lighting and thermostat and other systems in the house. I designed the house infrastructure to be computer-like, including states and conditional actions.
