Change is hard, and adopting collaborative tools is even harder because of the implicit threat to employee's flexibility in doing things themselves, keeping their failings secret, and maintaining some control through limiting information exposures.
And then there are companies that embrace collaboration. Last year I came across a remarkable little company using QB, salesforce Excel and Google Docs. They were all in the cloud except for QB on a local computer. The rest of the machines were all Apple, running CAD and design software. They managed orders, production and delivery entirely through Excel collaboration stored and shared in Google Docs. There wasn't a fit there for us, but it was an impressive operation from that perspective.
