At my workplace, the default office install on all new machines deliberately sets the default Office Save types to .doc, .xls, and .ppt because people want that compatibility when exchanging files with colleagues and coworkers around the globe. So it's not just people who haven't upgraded that want to save and create files in .doc

If this applies to Google Drive as well, I am so out of there.

To paraphrase Cory Doctorow, "The best thing about a book is that I can own it". I can't give away an e-book, or loan it to a friend, or (usually) check one out of a library. Until these things change, I'm staying with paper.
