Tablet demographics

ComScore's latest research on tablet owners is finding some differences among the profiles of iPad, Android, and Kindle users.
  Their report suggests that the iPad remains the dominant tablet platform, accounting for more than two-thirds of the tablet market.  The biggest demographic difference between iPad and Android-based tablets is in income, with almost half (46%) of iPad users reporting annual household income of $100,000 or more.   In contrast, only about one-third of Android (325) and Kindle (33%) owners reported that level of income.  iPad users were also slightly more likely than Android users to be male (53% for iPad, 51% for Android).  In contrast, most Kindle Fire users were female (57%).  iPad users were also slightly younger, with 44% reporting they were 35 or younger, compared to 44.5% of Android users.  Again, Kindle users were a more distinctive demographic, with only 32% falling in the 35 or under age demographic.
  The distinctiveness of the Kindle demographics may be a reflection of its primary design focus as a media display device, rather than more general digital mobile platform.
  Another point of differentiation was what users reported as their primary reasons for buying one type of tablet over another.  For those choosing the iPad, the availability and selection of apps was their primary motivating factor for buying the iPad.  Android and Kindle users, on the other hand, rated price as their top consideration.
  The study also showed that owners of mobile devices were generally very satisfied with their devices. Using a 10-point scale, mobile device users reported an average level of satisfaction of 8.6.  Breaking this down by device, iPad owners had the highest satisfaction scores (8.8), followed by Kindle owners (8.7, Android tablet owners (8.2), and smartphone users (8.1).
