It's impressive to see them hit this mark because they've emphasized quality over quantity. (To a point. Of course, their filter criteria are pretty arbitrary, and they've let questionable apps through anyway.) If they'd simply wanted high volume, and let a bunch of garbage into the app store, they might have hit a billion downloads quite awhile ago.
