I'm not so sure about that ;-) My setup is simpler than yours:

I do all my development on one machine - a macbook pro (Tiger, haven't got around to upgrading yet).

I run only three applications pretty much all the time, and they're all full-screen - Firefox, Emacs and iTunes, and alt-tab between them. Occasionally I also start a Terminal, if I want to ssh into a server somewhere.

Usually my Firefox tabs are gmail, yammer, ganglia, http://irc.justin.tv, and often some documentation to help with whatever I'm working on.

Typically I have a dozen or so Emacs buffers open - mostly python, javascript and haxe source code.

I never write notes by hand. I either write them in an Emacs buffer, or I send myself an email.

This is where I work (at justin.tv): http://abstractnonsense.com/workspace.jpg
