My university uses Linux. We have linux workstations at the lab and Open Office and Gimp. It is fully compatible with my windows laptop. We use all office machines correctly and no problems. They switched to Linux in 2006.
Actually, many companies use linux for their servers! Sometimes, they use both linux and windows. I don't think it is a finantial problem... Decision-making in companies is so complex... It does not simply depend on a "let's use linux". People should decide together what they need and why and who can maintain the thing... That's all
