So skewing the data we have:
1. Android-based dumbsmartphones, with huge numbers in SE Asia
2. Millions of smartphones used dumbly (no insult to your dad intended, OK?)
3. Android activations on devices that are not smartphones are counted (Nooks and the like, with Fire soon to come)
4. All iOS devices not included
5. Differing behaviors between (average) iOS buyers and (average) Android buyers
6. Android activation numbers have an unclear relationship to devices sold
7. Web apps screw up the data collection
8. Siri and other aggregating software will increasingly foil the data collection
9. Tracking by browser is no indication of device used
10. and on
11. and on and on
12. and on and on and on.
Looks to me like there is no good way to know.
The only important data is...
Follow the money:
1. Device sales $$
2. Profits from device sales $$
3. App sales $$
4. Mobile advertising $$
