I'm sure the number is accurate and kudos to Google but, wow, who the heck is activating all these devices? From the people I run into I would estimate the iOS:Android ratio at 10 or 20 to 1 (San Francisco).
My day job we have 2 holdouts still using iOS, the rest went BB->iOS->Android. 2 of us went BB->Android direct and based on our experiences we eventually converted the rest.
At a contract site I work at, out of 15 people on the team, only 1 has an iOS, the rest have some kind of Android variant (with 1 having a BB) two have switched from iOS to Android in the last 12 months. I wouldn't say there's significant peer pressure to switch, they just go to the store and end up with an Android device, so I expect carrier pressure is the source.
An inspection of the rest of the organization (about 500 people), shows it to be about 70/20/10 Android/BB/iOS.
At my startup we're 100% Android, but considering getting a couple iOS devices for development, but not day-to-day usage.
I have 3 friends who are Apple diehards, you'll get their iDevices out of their cold dead hands. But the rest are currently Android users, with one switching up phones every so often just to see what the other side has.
Coffee shops and trains around here (D.C.) show mostly Android phones and iPads. Very rare to see an Android tablet in the wild. iPhones are not too uncommon, but seem to belong to the younger, hipper crowd.
Estimations from China:
- In my office, a Web company: Android vs iOS is maybe 30 - 70
- In the subway, Android vs iOS is more like 80 - 20.
