As someone who’s dismissed Office’s continued relevance, I would be remiss in not noting that 12 million is a large number. It’s way bigger than 500,000, for example. Even bigger than 4 million, by some factor that has yet to be determined by mathemeticians.
On the other hand, as a noted Internet jerk, I would also be remiss in not noting that the apps are free, that the number counts each app individually and that while I downloaded Word and Excel, I’m not going to buy them.
So, really, it’s more like 11,999,998.
