According to an IBM report, consumers with iPads made up 10% of all online shopping over the 2012 "Black Friday" consumer binge. This is an interesting statistic, but there's not a lot of context. It's unclear how much of this traffic translates to actual purchases. It also mentions people who shopped in-store while checking prices online on their mobile devices at the same time. How was this tracked? How accurate is their tracking method? What sites were they checking? How did this affect their purchasing?
This report seems to generate more questions than it answers.
