WWDC 2011 iCloud – Available this fall, iTunes in iCloud gets automatic downloads via all devices with one switch. The PC has worked well for the past 10 years as the digital hub for your digital life, but Apple says it hasn’t kept up because devices have changed because you buy on one device and have to sync to another device. No longer, as Apple’s iCloud brings all access to the cloud for free.
iCloud simply stores your content in the cloud and wirelessly pushes it to all of your devices as well as is completely integrated with your apps. It all happens automagically. Mr. Jobs also made reference to MobileMe and that it didn’t work, but that they learned from it. They’ve thrown out the past and have built and rewritten from the ground up to be iCloud apps.
