I once had to work a 5-hour production issue in a Hilton hotel room. The temperature, desk ergonomics, and lack of distractions (people or things) led to nearly superhuman levels of efficiency and clarity of thought. This solidified my view that open floor plans and cubes that are only a few feet high are absolutely horrendous for getting any work done. It perturbs me that offices are wasted on management that is typically in meeting rooms 90% of the day and thus can't take full advantage of them. I'm an extrovert too, so I can't fathom the annoyance of people who really don't like being in a crowd.
