I just had a thought:

Chrome OS threatens the IT department (as it currently exists) for many companies as with a redundant network connection, it basically eliminates user system maintenance, which can be a large chunk of IT's time (assumed).

It would be interesting, if one of the major opponents to Chrome OS would be IT staff that fear the loss of their jobs. IT staff may worry for the loss of their positions in that there would be far lesser demand for them.

Of course, this opens a new market, migration of services to web-tools and intranet development, and intranet maintenance.
