Are iPad 3 Wi-Fi Only tablets more popular than 4G versions?

  An American company specialized in analyzing applications for iDevices thought of making some statistics for the iPad 3 tablets sold by the Apple company. They claim that 89% of the tablets sold by Apple are Wi-Fi Only versions and only 11% would be the version equipped with 3G/4G. The company bases its claims on information obtained from the time spent by users in applications that contain a special software of the company and it seems that only 6% of the internet connections from the applications would be based on a 3G/4G data connection.

  Moreover, most of those who own a 4G tablet use the Internet via Wi-Fi more often and it is normal to be like that considering that Internet subscriptions are not that cheap. What kind of tablet did you prefer to buy and what kind of connection do you use more often?
