Even for a company that has mastered the art of product-launch hoopla, Apple Inc. appears to have pulled out all the stops for its iPhone.

Technology analysts say Apple started its publicity campaign for the iPhone uncharacteristically early, first showing off the device six months ago and stoking the media feeding-frenzy since then with incremental announcements that have kept the sleek combination of cellphone, multimedia player and internet browser in the news.

No Canadian launch date has been announced, but the iPhone goes on sale Friday in the United States. Diehard Apple fans are expected to line up overnight or longer outside retail stores to get their hands on an iPhone, which starts at $500 US.

But skeptics wonder whether even the most innovative product could live up to the iPhone's lofty expectations — and whether the pre-launch anticipation has spiralled too far out of control. Scrutiny of the product is so great that any small disappointment could send Apple's stock plunging, experts say.

Technology analyst Mike McGuire said Apple fans have elevated the status of the iPhone to unprecedented proportions — "somewhere between electricity and sliced bread.

"The blessing is you've created an amazing amount of demand. The curse is you have a very high level of expectations to meet," said McGuire, a research vice-president with Gartner Inc. "If there's a misstep, there will be a lot of gloating people in the industry."

Apple claims the iPhone will be easier to use than other smart phones. It has a unique touch-screen display, and intuitive software that allows for such user-friendly features as scrolling visually through voice mail messages and easy access to the internet and video and music libraries.

Applause and controversy

The hype began when Apple CEO Steve Jobs took the wraps off the iPhone at the annual Macworld Conference and Expo in early January. The dramatic introduction — accompanied by thunderous applause and a standing ovation from thousands of Apple aficionados at a San Francisco convention centre — was followed up by a public relations blitz and hundreds of articles in blogs, trade publications and the mainstream media.

The iPhone stayed in the news for weeks after the launch, thanks in part to a trademark-infringement lawsuit by Cisco Systems Inc. over rights to the name. Cisco said Apple's use of the iPhone name constituted a "wilful and malicious" violation of a trademark that Cisco has owned since 2000.

In late February, San Jose-based Cisco — which sells a line of Linksys iPhones that make free long-distance calls over the internet — and Cupertino-based Apple agreed to share the name.

Apple's iPhone returned to the forefront of newspapers and websites in May, as the company stock reached record heights and many Wall Street financial analysts said the sleek iPhone could be a profit-generating machine, similar to Apple's iconic iPod.

The iPhone has already generated a thriving cottage industry online, with more than 1,100 peripheral iPhone items currently for sale on eBay, including colourful holsters, touch-screen protectors and car adapters.

But the hype has also hurt Apple.

The launch is being so closely watched that Apple's share price plunged more than four per cent in a matter of minutes last month after a rumour about a delay was reported on Engadget.com, an electronics website. The rumour was quickly corrected by Apple, and the stock largely recovered by the end of the day.

"That just shows how powerful this has become," said Chris Hazelton, analyst with market researcher IDC, who said the amount of hype is "almost dangerous to the success of the device.

"God knows what's going to happen when the reviews come out," he said.

Few reviews

Diehard fans are expected to camp out in front of Apple and AT&T stores to get a shot at snagging one of the iPhones, which are being sold on a first-come, first-serve basis starting Friday evening.

Apple has been famously tightfisted in limiting the number of review units before a launch, and the iPhone is an extreme example of the lengths the company will go to keep its prized gadget under wraps until the last minute. So far only a handful of reviewers are believed to have gotten units to try out.

Dan Frakes, senior editor at Macworld magazine, said he will be one of a half-dozen writers and editors from his magazine queuing up early Friday. He hopes to buy an iPhone so he can write a product review.

But like many people debating whether to buy the iPhone, he still has questions about whether the device can live up to the heightened expectations.

"If it works really well and does all these things well, I'd have no problem buying one on my own," he said. "That's the question out there right now — no one knows."
