Apple iPhone, iPad are "Gateways" to Apple Ecosystem

Though in the past the apple iPod was a "gateway" device introducing users to the Apple ecosystem, that role now is played by the iPhone and iPad. About 25 percent of iPad owners say the device is their first Apple product.

According to the NPD Group, 33 percent of U.S. homes, (37 million households) own Apple products. While a majority (69 percent) of these consumers own iPods, ownership of iPads is growing.

“iPad sales are growing much faster than any other Apple product has this soon after launch,” said Ben Arnold, director of industry analysis at NPD. ”In fact, one-in-five Apple owner households has one, nearly equivalent to the number that own an Apple computer."

Historically, the iPod has been the introductory Apple device for consumers, with 82 percent of owners saying it was their first Apple product.
