Fun fact: Android will reach 1 billion cumulative devices sold in 2013, and an estimated 2.3 billion in 2015. Apple is estimated to reach 530 million cumulative in 2013 and 1 billion in 2015.
In other words, there will almost be shipped more android devices this year, than apples cumulative number of iPhones made.
Oh my god, then there'll be 9 billion Android devices in use by 2018... WOAH!
Seems you ignored what i clearly said: Android devices are always lagging behind in the adoption of the most recent version of Android.
Of the 750 million Android devices activated there are only 16.5% running Android 4.1 and more than 50% aren't even running Android 4.0, the "Finally less ******"-release.
16.5% of 750 million = a bit less than 125 million devices capable of running Google Now.
When Google releases Google Now on iOS, it will most likely run on any iOS 6 device - that's more than 300 million, including sales in this quarter the number will reach 330 million or more.
The day Google Now is released on iOS, more than SEVENTY percent of the devices capable of Google Now are iPhones, iPads and iPod Touch.
That should make every Android fanboy ultra-sad, because it show's that iOS is still the dominant mobile OS.
Not in mumbojumbo market share, but in all points that count, like actual usage as a smartphone, instead of usage as a feature phone or in this case - features available to the most people.
Whatever feature Google will anounce for Android 5.0 during I/O 2013 - they will be available to the less than 20 (actually, 10 million is more likely) million people who bought the Nexus 7, Nexus 10 or Nexus 4 til then.
iOS 7?
100 million users a week later, 300 million after 3 months.
