Two thirds of US Tablet owners have used the device to watch full-length movies

"A recent study of over 1,400 U.S. consumers conducted by Boston-based custom research firm, Chadwick Martin Bailey found that smartphones and tablets are not only more popular than ever, they are replacing relatively new technology like portable gaming systems as well as devices that have long resisted substitution like TVs and laptops.
The increase in quality and capabilities of mobile devices has sparked major changes in consumer habits. For example: over half of smartphone and tablet users play games on their device and two-thirds of these people are using other devices less for gaming (particularly portable gaming systems). Additionally, nearly two-thirds of tablet owners have used these devices to watch feature-length movies. As tablets become more mainstream, the data indicate that stand-alone DVD players will go the way of the horse and buggy.
“The increasing ubiquity and capabilities of smartphones, tablets and the mobile networks that support them is having enormous implications for the entertainment and consumer electronics industries,” says Chris Neal, Vice President of Chadwick Martin Bailey’s Tech and Telecom Practice. “Content owners and advertisers of all stripes stand to benefit, while many specialty device manufacturers will need to course correct if they haven’t already.”"
