I sincerely feel with those who can not concentrate in an open environment but all is not black and white. As a mild introvert I hate the whole social dance associated with entering someone's private office while I can go into a deep concentration wearing just over the ear headphones even if I forget to start the music.

(Ideal is the combination of open space with numerous meeting rooms and smaller pods for phone calls and occasional privacy.)

Productivity is not that important if you are producing the wrong thing in the first place.
