During this week’s Worldwide Developer Conference, Apple announced its new cloud storage service, the creatively named iCloud. To grossly oversimplify the matter, iCloud is an evolution of Apple’s three-year-old MobileMe service …except that iCloud doesn’t cost $99 per year. It will be free, unless you want to sync music between devices that you didn’t buy from iTunes. (That costs $25 per year.) Apple plans to kill MobileMe on June 30, 2012, and current members won’t have to pay to renew their subscriptions. That’s pretty great, unless you’re a subscriber who handed over a hundred bucks to renew just a few weeks ago.
