2010s – cloud is the digital hub
As Apple started the initiative of using PC as the digital hub, it also ended it with the iCloud. And that's not without reason. Every day, mobile devices are coming closer and closer to match PC capabilities. It is time to demote the PC to be just another device on par with mobile devices. Now, cloud is the new digital hub where everything gets stored and synced to it. Add or update calendar items, contacts, notes, e-mails, photos, songs, videos, books, and it's all available in the cloud and immediately synced across devices. iCloud was the first notable initiative of positioning the cloud as the digital hub.
For the sake of history, iCloud is not Apple's first attempt in the cloud computing space. There was MobileMe that offered similar synchronization services for an annual subscription fee. MobileMe's primary purpose was to keep certain files synchronized among multiple devices that included e-mails, contacts, calendars, browser bookmarks, photo galleries, and Apple iWeb and iDisk services. The MobileMe service was discontinued entirely on June 30, 2012 and replaced by iCloud.
