Roughly 17 percent of the homes with an iPad have two or more tablets, a YouGov study claims. The research firm polled 1,667 tablet owners, of which 782 said they had an iPad, and 145 said they had at least one more tablet. Use by other people is said to be primary reason for having multiple tablets; 37 percent of iPad owners explained that a partner uses the iPad "all the time," while 17 percent cited family members, and 14 percent mentioned children.
