Apple had kept the market clueless by not revealing the details of ‘the upcoming cloud service offering’, since the announcement of unveiling Lion, iOS 5 and the iCloud.

Apple’s iCloud has been anticipated to have a network that can take some processing and traffic burdens from wireless carriers' networks. Unlike its usual practice, Apple this time has revealed in advance about the launches and will provide further details at an event in San Fransisco on Monday.

But the question is will it be a hit or miss. If Jobs cares about it is usually great. But Jobs has been on medical leave for months. So if it is from Apple there is a fair chance that it will stink.

With the unparalleled success of both the iPhone and iPad, Apple has become celebrated for sleek devices that fly off the shelves. But deep in the annals of Apple history are a number of products that were, put simply, commercial flops. With all eyes now focusing on the potential release of iCloud, it might be a good time to take a look back at some of Apple's product or services disasters.

Apple shares surged around 6000 percent since Jobs became CEO in 1997. But it did not come by its present success easily. Before the iPod, iPhone, and iPad became profitable icons of high-tech fashion in the emerging technologies space, Steve Jobs suffered a long series of failures.

Here are the top 5 failures:

MobileMe:

The launch of the revamped MobileMe at WWDC 2008 on July 9, 2008, which was essentially an upgrade of a pre-existing service called .Mac, had invited disappointing media review, promoting Jobs to sternly castigate the product executives.

You've tarnished Apple's reputation ... You should hate each other for having let each other down... Mossberg, our friend, is no longer writing good things about us, Jobs said at a meeting of product executives in the Apple campus.

He also used the 'F word', angered by the poor review the product got from The Wall Street Journal's Walt Mossberg, according to an AppleInsider report. Jobs then went on to disband the original team that revamped the service.

iPod Hi-Fi:

iPod Hi-Fi is a speaker system developed and manufactured by Apple Inc and was released on February 28, 2006, for use with any iPod digital music player. The stereo system was quickly discontinued after lackluster reviews, a high asking price of $349, and disappointing sales.

Apple hockey puck mouse:

Steve Jobs exclaimed that the hockey puck mouse was the best mouse ever created. In reality it was Steve Jobs exclaimed that the hockey puck mouse was the best mouse ever created. The circular form of the hockey puck mouse has disappeared but it still makes appearance in a variety of Worst Tech Products in History lists.

G4cube:
The Power Mac G4 Cube was a small form factor Macintosh personal computer from Apple Inc, which was sold from 2000 to 2001. But its high price tag of $1,599 prevented it from actually generating a significant amount of sales.

Twentieth Anniversary Macintosh:

The Twentieth Anniversary Macintosh is a limited-edition personal computer that was produced by Apple Computer, Inc., in 1997 in celebration of the 20th anniversary of the company. It was met with lukewarm sales for its high price tag of $7,499. Despite drastic price cuts, Apple killed the product a year after launch.
