What Are the Activities, Behaviors and Attitudes of eReaders and Tablet Owners?

According to the GfK MRI iPanel, the top 5 Types of Apps used by Tablet owners in the last 30 days are Games, Social Networking, Weather, Music and Entertainment.  While not quite as popular, more than one-quarter of Tablet owners used a magazine app in the last 30 days.  Considering the fact that there is not yet a dedicated newsstand in the Apple app store, and that many magazines have not, to date, created a Tablet app version, this is a faily strong showing.
