Yep! I think Microsoft lulled people into a false sense that they weren't doing anything with Office, while the Google suite gradually gained features (and to be fair, does 90% of what a normal person would ever do with documents). But it turned out they were busy making every feature in Office work in the collaborative environment, with versioning. It's incredibly impressive, and I am not a natural fan of Microsoft. It doesn't work as well as Google with a crappy or nonexistent Internet connection, but in your typical office environment it's great. I think people will be really surprised at how easily you can do things like assemble slides for a collaborative presentation. Sharing with people outside the organization requires a Microsoft account of some kind (either institutional or your old Xbox Live or Minecraft account) but that's about it. A high fraction of everything can be done in the browser, so it's easier than ever to have a Linux desktop. Plus have you see they have LateX equations now?
