Cloud Computing

The "free" iCloud reminds us of Apple's real business model. Against this tattered backdrop, iCloud walks on stage.
The most striking difference with MobileMe and other web-based offerings already mentioned, is the shift away from the browser. I'll use a word-processor document to illustrate. In both cases we'll assume you've already stated your credentials, login and password for Google, Apple ID, and password for iCloud. With Google Docs, you fire up your browser, enter the URL for your service, compose or edit a document, file it in a folder in Google's Cloud, and it's ready for you from any computer anywhere.
