According to Google:
- 100 million Android devices have been sold, more than Apple…,
- 36 OEMs, 215 carriers, and 450K developers push Android/Linux,
- 310 different devices sold in 110 countries,
- 400K activations daily, 4.6 per second,
- 200K available applications exist, and
- 4.5 billion installations of applications have been done, an average of 45 per device.
If that does not get your attention, consider that the rate of uptake is still increasing… at about 100% per year. 8-()
Naturally there are limits to growth and the performance of Android/Linux could max out upstream suppliers real soon. Assuming supply gets fixed, eventually everyone from 8 to 80 will own one. That would only take 3.4 years at the present rate. I imagine this all will accelerate as the price of smart thingies decreases. There is no way this growth in use of Linux will somehow be confined to smart thingies. All forms of computing will shortly be involved with Linux if they have not already been.
