What I'd like to see are new STUDIES about open offices, not the rehashing of personal experiences and anecdotes.
The article we're discussing mentions multiple studies...beyond that there's a great New Yorker article[1] from last year that references a number of studies. This blog post[2] links to a couple others and addresses costs/alternatives.
A "study of over 40,000 survey responses collected over a decade has found that the benefits for workers are quickly outweighed by the disadvantages"[3]. A Washington Post article[4] on office furniture designers realizing (citing multiple studies) "open-plan spaces are actually lousy for workers." And a TIME article[5] highlighted decades of research that associated open layouts with "greater employee stress, poorer co-worker relations and reduced satisfaction with the physical environment."
