Their opinion is also behind on LibreOffice, too. I won't defend GIMP's monstrosity, but I finished a whole dissertation, do all my regular spreadsheet work (that isn't done via R), and have created plenty of visual mockups with LibreOffice. Plus, I don't have to deal with a spammy Windows environment.

Sure, we use Google Drive, too, but that's just for sharing documents across offices, not for everyday use. For that, the open source model is a clear winner in my book.
