The straight demographics are hard to argue with—on average, iPhone users do tend to be slightly younger, wealthier, and better educated than users of BlackBerrys or Windows Mobile devices. But the “more productive” conclusion is totally erroneous: It’s based on the fact that iPhone users are more likely to use the Internet at least once per week, which in our definition is most certainly not a rubric of productivity. I’ve spent entire weeks on the Internet and all I’ve produced is the beginnings of a bed sore and maybe an extra five pounds around the waist.

The survey was, obviously, taken before the introduction of the $US99 iPhone, and we’re all curious to see if the slightly-cheaper option will impact the iPhone’s demographics. Ted Schadler, who commissioned the study, promised to revisit it later this year to see if there’s been any change. Until then, enjoy your iPhones, Supermen and Superwomen. Just try not to use them while you’re flying to work, it’s dangerous. [AppleInsider]

According to Hitwise data and this Lifestyle Quadrant Analysis, while lots of people are using Yahoo search (those are the dots in the upper left), groups that have spent more that $500 or more online tend to use Google (those are the dots in the lower right, the bigger dots designate $500+ spenders). So while Yahoo has the “struggling societies” market cornered, Google is fairly pleased with their “affluent suburbia” and “upscale America” user base.

So what do you think of the stats, are you aptly represented? [hitwise via techcrunch]
