Using cubicles a symptom of a sickness would mean that Google and FB are sicker. Intel has better workstations.
As an example, my current cube at Intel has walls all around (albeit short, but some buildings have walls taller than most people), 2 file storage cabinets with a fair number of drawers, a decent sized desk (enough for 2 people, not that we'd do that). Correspondingly, the cube is enough for 2 people. Also, I have a whiteboard.
