Here's a wrinkle in the story of Android taking over the world.

Both IBM and Adobe are reporting that Apple's iOS, which powers iPhones and iPads, is destroying Google's Android in mobile shopping on Thanksgiving and Black Friday.

IBM says it tracked "millions of transactions and terabytes of data from approximately 800 U.S. retail websites" on Thanksgiving and Black Friday.

It broke out an analysis of iOS and Android:

On average, iOS users spent $127.92 per order on Black Friday compared to $105.20 per order for Android users. iOS traffic reached 28.2 percent of all online traffic, compared to 11.4 percent for Android. iOS sales reached 18.1 percent of all online sales, compared to 3.5 percent for Android.

This is astounding when you consider that comScore says Android has ~52% of the smartphone market, and iOS has ~42% of the market in the U.S..

Adobe also has an analytics tool. It tracked "400 million visits to more than 2,000 U.S. retailers’ websites on Thanksgiving Day and Black Friday."

Here's Adobe on iOS versus Android:

iOS-based devices drove more than $543 million dollars in online sales, with iPad taking a 77 percent share. Android-based devices were responsible for $148 million in online sales, a 4.9 percent share of mobile driven online sales.

...iPads drove the vast majority of online sales with $417 million while iPhones were responsible for $126 million. In comparison, Android-based phones generated $106 million, Android-based tablets $42 million in online sales on Thanksgiving and Black Friday.

These are both measured in the U.S., which is a unique market for iOS. However, this is still a jaw-dropping gap in usage between the two platforms. It suggests that the focus on smartphone market share misses a bigger picture about how the platforms are actually used.
