Err.. how is that like what MS has talked about? The Explore button in Google Docs has absolutely nothing to do with document formatting, smart or otherwise.
Just checked it out with a new doc and an old one - it's dumb as a doorbell and basically is the same as Googling for info about random topics within the document using your phone.
A year of Office 365 Personal can almost always be had on OLX for R250-350. And that's including 1TB OneDrive storage, which will probably increase sometime seeing as all major cloud storage services have doubled the 1TB accounts.
Is that not cheap enough for you?
I don't understand Google, they keep removing/reducing features.
They used to have a really great harvard referencer, you just start typing the name of the article and it gets the full thing for you, tied in with Google Scholar. They have it as a footnote thing, not as great.
You use explore > search the item, then hover over and select the thing that pops up, it then adds the number to where you're typing and adds the reference to the foot of the page.
It's still a lot better than MS one, that one is a pain to add stuff to, spend a good ten minutes just referencing 3/4 papers if there are multiple authors. Google's one also supports other formats, but I usually use Easy Bibliogaphy.
Google Docs doesn't have Harvard referencing anymore:

This was after they removed it and brought it back, before removal it was there, now it's gone. Also no more support for direct Google Scholar to be able to fetch the authors as well (could be the papers I am searching though as getting it through Books24x7).
