Workstation setup and ideas

Hello,

Just curious as to what people find to be the most ideal configuration for their workstation. I'm an Accountant(private/corporate accounting) and I currently have my desktop extended to 3 monitors(typically Outlook is on the left, Excel is on the main screen in the middle, and company software and/or web-browser is on the right), a Logitech wireless Wave keyboard and a Logitech wireless trackball M570. Thanks to the Logitech software, I have all of the extra buttons on the mouse and keyboard as well as all of the F-keys assigned to various tasks for one-click access. Before I realized that I could also assign the F-keys with the Logitech software I was actually thinking about buying a gaming pad like the Razer Orbweaver or Logitech G13.

I also use Dvorak as my keyboard layout.
