The chart totals over 100% because respondents were allowed multiple choices. That’s too bad because it skews things a bit. Yes, the iPad is stomping everyone, but 94.5% has less meaning when the total comes to nearly 150%.
It’s better to look at this one column at a time, where we can determine a device’s absolute rejection (not acceptance). For example, we don’t know that 3.8% of respondents would buy a RIM PlayBook, because it may have been their second choice, but we do know 96.2% of respondents rejected it outright, since it’s not on their list at all.
I think of the beatdown like this: for each iPad competitor (column), 90% or more of respondents rejected it. In other words, nine out of 10 people wouldn’t even put it on their list as a second choice. Meanwhile, the iPad is rejected only 5.5% of the time. Put it all together and we know not only that the vast majority of respondents are interested in the iPad, but that for most of them there is no Plan B.
