Apple tipped its hat early, but now we have the details from the man himself. “iCloud stores your content in the cloud and wirelessly pushes it to all your device. It automatically uploads it, stores it, and pushes it to all your devices.” And by “automatically,” he means it: in addition to every day content, such as purchased music, books, photos and videos, device settings, and app data that will be automatically backed up over WiFi, Documents in the Cloud will effortlessly sync Pages, Numbers, and Keynote data between all of your iOS devices. There will be no advertising (contrary to previous rumors), and calendar, mail, and contact sync is free (for up to five gigs of mail). Also in store is the new PhotoStream cloud feature, which is essentially a gallery in Photos that exists on all of your iOS devices, Apple TV, your OS X and even your Windows PCs, and syncs through the cloud. Take a picture on your iPhone and it appears on your laptop and your iPad, and it’s stored in the cloud for thirty days. iCloud will be released concurrent with iOS 5 this fall.

If that isn’t enough, Apple has announced iTunes Match, a service that scans your iTunes library library and populates your iTunes in the Cloud account with any of your previously bought and ripped music with 256Kbps AAC, DRM-free files (as long as the titles appear in the iTunes store). To be perfectly honest, in all the excitement we’re having a hard time mourning the loss of MobileMe, which is dead as of today, according to one Steve Jobs.
