Horace Dediu at Asymco offers up a thought-provoking post today that questions why iOS users are so much more likely to use their devices to shop than Android users. Using data from IBM’s Digital Analytics Benchmark, Dediu finds that the iPhone and iPad accounted for 74 percent of mobile traffic on Black Friday, and Android gadgets (aside from the Kindle and Nook) drove 23 percent of mobile traffic.

Dediu floats a few suggestions why iOS users are so much more active on their devices, including the fact that the iPad “is changing shopping habits” and the theory that later adopters who buy Android gadgets are simply less inclined to use the mobile web. But I think one big reason is that so many Android devices are simply less user-friendly than the iPhone and iPad. Apple rightly gets flak for controlling its ecosystem so tightly, but there’s no question that the tight control makes for a top-notch user experience. And a lot of users are more than happy with that trade-off.
