SEATTLE — People who lined up to buy the first iPhone knew what they were paying hundreds of dollars for: a new cell phone that promised to be better. Apple Inc.'s newest gadget, the iPad tablet computer, falls into a category that's foreign to most people.
And yet plenty of them have already happily dropped $500 or more for a device they've never seen, in the hopes it will be some previously unidentified missing link in their digital lifestyles.
"If Apple sold groceries, I would buy groceries from them," says Matthew Rice, who works for pharmaceutical company Merck & Co.
Apple won't say how many iPads it has sold in advance of their debut Saturday, and it's hard to predict how many enthusiasts will camp overnight and swamp Apple stores when the doors open Saturday at 9 a.m., as they did for last summer's launch of the most recent version of the iPhone. That happened even though people could "pre-order" the device, just as they can for the iPad.
Rice won't be ripping open any boxes Saturday, but only because he chose an $829 iPad with a "3G" data connection, which won't ship until late April.
He has owned four iPhones and just about every model of iPod ever produced. He uses an iMac computer at home and a MacBook Air laptop on the road. He jokes about giving Apple his credit card number and having the company just ship new products as they're released. But despite his near-complete catalog of Apple goods, Rice can find holes for the iPad to fill.
It will be perfect for carting around PDF versions of scientific articles he needs to read for his job, he says. And Rice, an avid photographer, hopes it will be a way to hand people an "album" and let them flip through photos of his travels.
Will Zich, an 11-year-old, started saving money last year for a new iPod Touch, but changed his mind when the iPad was unveiled in January. He can rattle off all his reasons for wanting one, such as the e-book store, plus a bigger screen and faster processor than his iPod Touch. He says the iPad will be useful on road trips, and for playing games and surfing the Web early in the morning when the rest of the family is still sleeping.
To be practical, Zich says he might also bring it to school and use it to record homework assignments.
Other people don't expect to ever leave home with it.
Brian Herlihy, a 31-year-old financial analyst in New York, expects the iPad will offer him a way to read magazines, newspapers and maybe books without the clutter of paper, and as a Web surfing device that's faster to start up than his laptop. On the street or when riding the subway, though, the iPhone is a more appropriate size.
Media companies are betting that the iPad's larger size — its touch screen is 9.7 inches diagonally, compared to 3.5 inches on the iPhone — is one reason people might pay for news and information that is often free in other formats online. Indeed, Herlihy says he'd be willing to pay a moderate amount of money for a newspaper or magazine if it were delivered through some sort of outstanding application. Otherwise, he's content to read for free using the Web browser.
On Wednesday the Silicon Valley venture capital firm Kleiner Perkins Caufield & Byers said it is so excited about the iPad's potential that it is adding $100 million to its fund for investing in developers who make applications for Apple devices. The firm began its "iFund" two years ago with $100 million and has invested in 14 companies.
Kleiner Perkins partner John Doerr, an early investor in Google Inc. and Amazon.com Inc., said the iPad is "going to rule the world. It feels like you are touching the future."
But even Doerr has trouble explaining why people already equipped with powerful laptops, lightweight netbooks and fancy mobile phones will feel compelled to buy an iPad. "I don't think we can anticipate the great new applications and uses that will be created," he said.
Not only Apple die-hards have been swept up in iPad hype. It has also turned the heads of folks who have been lukewarm on Apple gadgets.
Nick Braccia, a creative director at a digital advertising agency in San Francisco, uses a BlackBerry phone and music player that connects to the Rhapsody subscription service rather than Apple's iTunes.
"If anything, I was always kind of 'anti,'" Braccia says. "I get a little annoyed with people standing outside for an operating system update. I have no patience for rabid fan-boy-ness."
Braccia, 34, says he thought the iPad would be too expensive for him to even consider. When he learned that the starting price was $499, he was sold. It didn't hurt that the iPad will come with electronic book-reading software, and can be used to replace the Nook e-book reader from Barnes & Noble Inc. his girlfriend monopolizes.
Braccia thinks he'll use his iPad for surfing the Web over morning coffee, for reading books and maybe watching movies. And he justifies it as a smart purchase for work, because his clients make video games.
"Professionally, I feel I should have at least one of those products in my pocket. Or my bag. Because an iPad isn't going to fit in my pocket," he says.
Not everyone is planning to make that kind of room in their lives for an iPad, of course.
Matt Jones, a 50-year-old video producer in Columbus, Ga., has a Windows Mobile smart phone. He doesn't pay for home broadband Internet access or cable TV, and he certainly isn't going to find a spot in his budget for an iPad. Plus, he already has plenty of gear to carry when he's working.
And when he's not, he says, "I wouldn't want to have to have a purse just to have the iPad."
