iPad Air may have accounted for 41% of all holiday iPad sales
CIRP sites a survey of 500 Apple customers, and found that out of all respondents who purchased an Apple product over the holidays, only 5% bought an iPad 2. Of those who purchased Apple tablets, 41% chose the iPad Air, and 16% chose the new iPad mini Retina. Given the availability issues that the iPad mini Retina faced, and given that the Air wasn't released until November 1st, and the mini Retina on November 12th, those are solid numbers for the quarter that spanned October through December. The original iPad mini still pulled in 25% of sales.
These are all interesting numbers, but the trouble is that they don't tell the whole story, not by a long shot. These numbers are specific to Apple sales alone, and don't really tell how Apple's tablets sold in comparison to the outside competition from Android and Windows makers. No doubt we'll be getting those numbers soon enough though.
