True. However they also say: "...enclosed offices need not be one-person offices. The two- or three- or four-person office makes a lot more sense, particularly if office groupings can be made to align with work groups."
I think there needs to be a balance between private/semi-private team space and individual private space within the team space.
I learned a lot setting up and administering my own Linux server (I have a Windows background), and use it to play around with various setups / tools.
