"Survey: 35% of U.S. Consumers Planning to Purchase Next-Generation iPhone"
Bzzt. Wrong.
Either the OP doesn't understand statistics or, more likely, Macrumors is trying yet again to artificially boost pageviews with misleading headlines.
35% of RESPONDENTS, which according to the original article do not appear to be random but self-selected online consumers, indicated they would purchase the next gen iPhone.
To put this in perspective, a sample size of 3000 even randomized is relatively meaningless as it's less than 1/1,000,000th of the US population. Even less meaningful when you consider that the sample is actually nonrandom, and that the particular set of respondents being online could easily have skewed the results skyward.
