Also as a related but possibly incorrect observation - it seems that there is usually more table space per employee in cubicle layouts than in open-space. Whenever I see open-space office pictures there are long rows of tables and each worker has a laptop, maybe one monitor and small place for notes and stuff. And right next starts another similar workplace. In 4-person cubicle I (and all the the others in the office) have place for 2-3 or 4 monitors, laptop in dock, heaps of wires, analyzers, stacks of device parts, normal keyboards and mice, plants and other stuff and have free space left.
