It’s something of a running joke in the tech press how often highly paid and influential analysts update their predictions for iPad sales. TechCrunch’s article by Erick Schonfeld from a couple of days back neatly sums things up:

The iPad sold three times as much as the average tech blogger predictions, and five times as much as the average Wall Street analyst prediction. Think about that the next time you see a prediction for anything in tech. The newer it is, the less anybody knows.

To be fair, Brian Marshall did OK guessing at seven million, but just 1.1 million, Doug Reid of Thomas Weisel and Yair Reiner of Oppenheimer? Really? Even if the iPad hadn’t become a breakout hit and shaken up the industry, it would have sold more than that number to Apple fans alone.
