I was surprised when a friend of mine who's an experienced user of iOS devices told me recently that he hadn't yet set up iCloud. When it first became available, I was eager to set it up, and have never looked back. I love it. If you haven't yet set up iCloud, Macworld has posted an excellent guided walking you through it. They cover signing up for an account, setting up your iOS device, setting up a Mac or PC, and setting up an Apple TV.
