I have a pc, a mac and a single iOS device.
I don't watch movies and listen to music muc on it - I have about 6 movies and 10 albums on my device. And I regulaly and automatically sync and backup to my mac several times a day.
I've not yet activated the iCloud function. Why not? What's the point? Should I. What actual benefits would I receive? What will it actually do for me personally?
