The story which The Atlantic quotes from in support of their 13 million consensus estimate actually says:
"The most pessimistic analysts are calling for sales of just 9 million; the most optimistic see sales of over 15 million. Consensus is for about 12 million, which would be a year-over-year increase of 155%."
Couldn't find a description on how consensus was derived (is it an arithmetic mean?). Depending on how much of an outlier the 15 million estimate was, 11.8 million actual sales might actually be above the median estimate.
Looks like Apple was well below the median, though PED says the 6 most accurate analysts he has been tracking had a consensus estimate of 10.95 million iPads.
