It is true that the consumer side is pushing the enterprise a lot currently, but things that are core to larger corporations like the OS, Office, and backend services are no easy thing to switch-up. That is why you still see lots of companies running Novell/GroupWise. Do you really think it is meeting there needs? There is no one else out there that can support enterprise software like Microsoft (I'm not saying they do a great job all the time) and that is what the enterprise customer is really buying into.
