The survey included more than 300,000 people, so the sample size is a lot better than most of the surveys you see in the tech business. The clearest results, in this edition at least, focus on users aged between 18 and 27. that's a prime demographic because they're the ones whose computing proclivities you're going to have to support in a couple of years, and for whom you'd better start planning.
They're not the core population in most U.S.-based companies, though.
In India, Indonesia, Nigeria and South Africa, more than 90 percent of respondents said they use mobile more than stationary hardware. The majority of U.S. -based users also use mobile more often (they're Opera Mini users, remember), but the split is 51 percent/49 percent.
