"I challenge anyone to point out a major flaw in our data"

its based on a non-random set of self selected participants who happen to use facebook.

That is a major flaw in your data.

Its useless to draw conclusions from it, unless you are specifically interested in drawing conclusions about iPad users who have a facebook account and like to fill in personality quizzes.

Having said that, if that small subgroup of iPad users is, in fact, the group that you wish to discuss then go for it, but please be clear about that at the top of your post.
