Are you using dual monitors? If so, how?

I'm super super jealous of Craig for having three monitors! I have two and I could NEVER go back to one. In fact, I started my current job in February after having worked for 3 years with dual monitors and when I got to my desk, the first thing I asked my boss was if I could bring in a second monitor. When you're incorporating comments, it is literally the best invention in the world. Here's my typical setup:

Monitor 1:

PowerPoint/Articulate Product Suite

Email

Monitor 2:

Word documents (client/SME comments, source material, etc)

Excel spreadsheets (source material, schedules, etc)

PDFs (source material)

Internet Explorer

Miscellaneous other junk

Now if I could only convince my boss to let me switch to Mac with Windows running in Parallels, my setup would be complete...
