I'm betting the two most complicated functions in the next iteration of Word will be "save document" and "print document."
I pick on Apple (I have good reasons!) but the only reason I avoid picking on Microsoft is that I've avoided (probably not for long) the last few rounds of upgrades. The history of Microsoft involves ignoring innovation, and then suddenly deciding that they need to integrate it into everything. "So people like notifications on their phone? That's pretty much all our new operating system will do! Remember Pointcast from 1997 or so? It's like that only more annoying! The internet of things! People want Facebook in their $800 toaster!"
