SAN FRANCISCO (RNN) - Apple CEO Steve Jobs emerged for a second time since taking a medical leave from the company in January to unveil Apple's cloud-based service at the company's Worldwide Developers Conference in San Francisco on Monday.
Apple's CEO, currently on his third medical leave, took the stage to James Brown's "I Feel Good" receiving a standing ovation and huge applause, and said, "It always helps, I appreciate that."
Jobs, dressed in trademark black turtleneck, unveiled Apple's free cloud-based service, iCloud to an enthusiastic crowd of developers.
"We are ready for our customers to start using iCloud and we can't wait to get it in their clouds," Jobs said.
The service ends the nightmare endured by Apple users for years of syncing multiple mobile devices and computers.
All files, pictures, music, mail, etc. will be available through the cloud, allowing users to wirelessly restore a new device simply by entering a username and password.
Jobs was most excited about Apple's Photo Stream service.
"It's going to bring the cloud to photos," Jobs said.
iCloud's photo support creates a feed of the last 1,000 photos and syncs them to all of your Apple mobile devices, iPhoto and even Apple TV.
Using iTunes through the iCloud allows you access to stream your entire music library (if purchased from iTunes Music Store) on all your devices, all the time.
But what if you didn't buy all of your music from the iTunes Music Store? Jobs has you covered - for a fee.
For $25 a year, iTunes Match will scan your music library, matching songs with Apple's copies already uploaded to the cloud.
Starting this fall, Apple's cloud-based service will give users 5 gigabytes of free storage for mail, documents and backups.
iPhone and iPad usability is heading to their bulkier counterparts with Apple's eighth edition of the their successful OS X series.
OS X Lion takes several hints from its mobile touch screen counterpart, iOS, by expanding Multi-Touch gestures on the track pad.
With a simple swipe, users may be introduced to the new Launchpad, an almost carbon copy of the application and folder layout currently used on the iPhone and iPad.
Another swipe and flick will open Mission Control, an updated version of Apple's workflow-boosting Expose. This update will ease the transition to-and-from new distraction-blocking full screen applications.
Get ready to receive some funny messages from your friends, OS X Lion includes the sometimes-adored and frequently-maligned autocorrect feature.
Other iOS-inspired updates include a new version of Mail, Auto Save and Resume, giving you the ability to restart your computer and have every application and window just the way you left them.
The newest version of OS X will be available for download exclusively from the Mac App Store some time in July, with a price tag of $29.99.
Just like the computer, Apple's mobile devices will get a facelift with iOS 5.
With the update to the mobile operating system, the iPhone and iPad are no longer slaved to a PC.
"We're living in a Post-PC world," Apple Senior Vice President of iOS Software Scott Forstall said, "Especially with the iPad, we're ushering in the Post-PC world."
Over-the-air updates and new photo-editing possibilities are helping Apple mobile devices find their independence.
Twitter is now integrated into the operating system, allowing users to input their Twitter username and password under the settings tab instead of in each individual app.
This integration allows users to share photos from the camera and links from Safari and YouTube directly without opening a second app.
With iMessage, iOS5 is also answering the challenge of Research in Motion's Blackberry Messenger.
The new messaging service will allow individual and group messaging of text, videos, contacts and pictures to be pushed to all of your mobile devices, allowing you to pick which device to continue the conversation on.
The new operating system comes with an update to how users receive alerts by creating the Notification Center. With a swipe from the top of the screen, users will find all alerts and notifications, including updates, stocks and weather.
With Newsstand, newspapers and magazines now have a home on mobile devices.
Much like iBooks, released in 2010, Newsstand will allow users to browse, purchase and buy their favorite periodicals.
The new app takes the iPad one step closer to print by allowing background downloads, which "deliver" subscriptions during the night so they're waiting to be read in the morning.
iOS5 will be available in the fall for the iPhone 3GS, iPhone 4, iPad, iPad 2, and third and fourth generation iPod touch.
