Web usage stats are notoriously unrelated to sales. The larger iPad dominates web usage many times over its actual percentage of sold devices, for example.
They also don't tell us about device usage if someone is into apps more than the web.
Now, personally, I used a 7" Android tablet for surfing the web quite a bit, because it was very portable. (When Jobs famously told his staff that tablets weren't good for anything but surfing the web in the bathroom, he missed a golden opportunity. ANYTHING that engages men in the throne room will sell like hotcakes. - grin- ) So from my standpoint, there was no doubt that the iPad Mini would do very well.
On the other hand, the women in my family (daughters, daughters-in-law, wife) rarely surf the web. They're far more likely to use apps (*). Therefore they would not show up in web usage stats at all.
So think about your family's usage of their devices. Do they actually surf the web and hit major sites that would show up on a survey? Or do they mostly use social apps? Or view movies? Or play games? Or read email? Or engage in IMs or texts?
I do think that for a long time, iOS had a nicer web surfing experience. Now, with Chrome and other browsers, it's more even.
(*) For a couple of years, my youngest daughter would only use Android tablets with Flash, because all her favorite online games were available that way. Now she's moved on to games like Sims, and the iPad. She also uses the YouTube app a lot, and that doesn't use the web either.
Just thinking out loud.
