I found an interesting-looking laptop stand called the Notebook Spyder this weekend when I was browsing office ergonomics stores on the web (some people browse bookstores, others look at cars... I'm not weird, really).
Anyway, the Notebook Spyder is a little stand to raise your laptop off the desk so the display is at the correct height and you're not slouching or peering down to read the screen.

The nice part about the Notebook Spyder is it comes with a document holder and cable organizers. It's sturdy enough to support a CRT monitor if you use an external display.
There are pictures of the Notebook Spyder here. (You can also order it for $48.)
