The French police seem to have had a good amount of success as well: http://www.zdnet.com/french-po...
There are probably always going to be use cases for the majority of users to be fine with Open or Libre office. Some specialized functionality in finance might merit excel. There is nothing I've found on Linux that easily replaces Visio or Project ( libre-project is fine for reading, but I've had many issues with creating them). It's what I use at home (lubuntu). At work, I do have to say I prefer Outlook/Exchange for integrated mail and calendar, but I could probably live without Word/Excel/PPT.
Here's to hoping Libreoffice and the other forks can continue to expand and refine their software.
