Okay, I'm spoiled. The place I work just gave the coders an early Christmas present in the form of a dual arm-display support. It's a WONDER to use!
Now, I know we're lucky enough to have dual-displays, but this made my day (week). I'm not normal in anything, I didn't position the displays together like they show in the pictures, I have my left monitor turned to page-display format (portrait) positioned in front of me, the right monitor is up and angled down for review of what i create(d) on my primary display. My desk, is clean.
For me, for all of us, this is a big win in that we spend so much time staring at the screen this allows for us to task our systems to our personality and work-style.
Yes, these are expensive. If you'd like something more consumer-level, check out your local Tiger Direct for a unit that suits your needs. This unit from Ergotron is very nice and can be adapted to support a laptop. They have others...
