75% of Early iPad Air Purchasers are People Who Already Own an iPad

According to PiperJaffray latest survey, 75% of the US early iPad Air purchasers already own an iPad. Only 58% of the last year’s iPad mini purchasers owned an iPad. What is the reason for such different figures?

Gene Munster of PiperJaffray says that:

Of the iPad Air buyers who already own an iPad (75%), only 18% expected to keep using the old device and essentially all of those users were owners of an iPad Mini. We noted a similar trend in our iPad Mini survey in that 76% of iPad Mini buyers expected to use the Mini along with their prior full-sized iPad. We believe this makes sense as the majority of consumers that already own an iPad seemed to be replacing it with the Air entirely, but viewed the Mini as a companion device to the larger iPad. In other words, if a consumer owns more than one iPad, it is more likely to be an iPad Air and an iPad Mini than multiple full-sized iPads.

Well, I guess Munster’s words do make sense. But personally I have no idea of why a person needs two tablets at once.
