>It's just a word processor
Actually, this should be where I stop. You're bringing it down to the bare minimum, acting like all word processors are the same and can do the same things. Have fun typing up a 10 page document on TextEdit, I guess, since it's "just a word processor".
>Buying Office every year
Weird, because they came out with a version in 2010 and then 2014.
>Renting Office
Office 365 does provide more than simply Office, but I'll let that slide.
>You haven't been talking about what Office provides
Office, to me, provides a few things. I like the SkyDrive integration that comes with it and 8.1. I like the ribbon interface. When it comes to word, I find that is has the best spell-check and the best grammar check. It keeps my formatting better if I move my work to a WSYIWYG website.
My defense of what Office actually does is to say that it does more and more efficiently than the competition.
