this article supports the argument that high income households are tablet users. this makes the most sense to me.
"Tablet ownership continues to be prevalent among young, wealthy males. ComScore found that 54.7% of tablet owners using the web in August were male, and nearly a third were between ages 25 and 34. Almost half were members of households that earned more than $100,000 per year."
