Today at WWDC, Apple announced iCloud, which is essentially a backup / syncing service for all your apps, documents, music, and other media. All users will get 5GB of free storage, boasts iWork / third party API (Evernote, etc.) compatibility, and automated daily backups. In summary, “iCloud stores your content so it’s always accessible from your iPad, iPhone, iPod touch, Mac, or PC.” More information. Click here for the first picture in gallery.
It gives you instant access to your music, apps, latest photos, and more. And it keeps your email, contacts, and calendars up to date across all your devices. No syncing required. No management required. In fact, no anything required. iCloud does it all for you.
