Yup. If I need to write a long document, I had better do it at home. If I need collaboration from a bunch of people, I should do that in the office. If I want to research a problem without interruption, home. If I want to be available to people casually (they don't feel it merits a ticket, which often means I will write one up for them) I need to be in the office. Different requirements, different environments.
