My company was to move completely away from Office to Google's suite of products 3 years ago. Except for just the few macro jockeys that required Excel. It's harder to get approval for an Office license now, but most people that had Office 3 years ago, still have it today (except for Outlook, that one is gone). It's really Excel that seems to keep people from moving to Google's product, though. Word and the others aren't that big a problem.
