Yes well, open office plans and cubicles are awful, no argument there. But a real office with a door can be attractive relative to the situation many people have at home.
- You get plenty of personal space
- My cubicle got both a whiteboard and a bulletin board, a locker, two trash bins, and enough desk space to comfortably fit a co-worker for short sessions of working together
- high walls discourage conversations, so it is actually quiet
The biggest disadvantage is artificial lighting - my cubicle was quite removed from the windows.
Ironically enough, I do have a door at home.
