In a break from typical Apple style, the California-based company has pre-announced some details of its new cloud service, iCloud. Apple plans to reveal product details at its Worldwide Developer Conference. In addition, Apple CEO Steve Jobs, taking a break from his medical leave, will provide details on two existing operating systems, iOS5 and MAC OS x 10.7 or Lion. Cloud-based services are quickly becoming a big part of the world of technology, but Apple has not been strong in this particular area. Industry insiders generally agree that Apple needs to compete effectively with cloud technology in the same way the company does with software and hardware.
