SEATTLE (AP) -- Now that the iPad is in the hands of early adopters, the hard work for Apple Inc. begins.

Eager customers intent on being among the first owners of this new class of gadgetry stood in long lines across the country Saturday. They seemed willing to buy first -- and discover uses for the iPad later.

In some ways, it was reminiscent of the lines and hoopla surrounding the 2007 launch of the first iPhone. The difference: People knew then that the iPhone would replace their existing cell phone, an appliance that has become a must-have for everyone from uber-geeks to stay-at-home moms.

With the iPad, which fits somewhere between phone and computer, Apple must convince people who already have smart phones, laptops, e-book readers, set-top boxes and home broadband connections that they need another device that serves many of the same purposes.

Many of the earliest iPad buyers say they will have a better idea of what they'll use it for only after they've had it for a while.

That didn't stop them from imagining, though.

Beth Goza has had iPhones and other smart phones, along with a MacBook Air laptop, yet she believes the iPad has a place in her digital lineup. She likened it to a professional tennis player owning different sneakers for grass, clay and concrete courts.
