I have one monitor aligned horizontally and another aligned vertically, and I feel this works better than one large monitor or a monitor that swivels between the two alignments. I think part of this is because with two monitors, it's possible to rotate them relative to each other (ideally, I think, you would want a spherical / parabolic / hyperbolic monitor and this helps approximate that), but it might be that if I had hotkey shortcuts to easily throw windows where I wanted them on a single large monitor (like xmonad) I would be able to get most of the benefit.
Continuation of: Spend Money on Ergonomics, by Kevin
Three years have elapsed since Kevin wisely told us to spend money on treating our bodies well. It may be time to check for new gadgets, to verify what has worked and what has not etc...
If you have purchased an item for this purpose, or intend to buy one and don't know which, tell here, ask here.
Nick Bostrom uses a mouse that looks like a plane controller joystick.
I've seen keyboards that bend sideways, that are concave, that are convex, and that look like a sphere.
At FHI, dozens of books are used so that computer screens stay at eye level or above.
But I am no expert and I have not looked myself, nor would know how to. So please share in the comments the best knowledge about:
Keyboards

Chairs
Balls to sit on
Pillows
Beds/Matresses etc..
Screens - Size, position, brightness etc...
Other household office items - Stairs, Handles, Shower etc...
