iCloud has been adopted at a rapid rate since it was made available four months ago, according to an announcement by Apple CEO, Tim Cook at the Goldman Sachs Technology and Internet Conference recently.
Just over three weeks ago at Apple's fiscal first quarter earnings call, Cook mentioned that iCloud had 85 million users, and in the recent interview he let everybody know the service had passed the 100 million user milestone. This can be translated into a growth rate of 17.6% in 21 days, TUAW observes.
iCloud was introduced to the market in October last year along with iOS 5 as a service meant for cloud storage that can also provide syncronization for calendars, address books, browser bookmarks and other applications.
Users also enjoy the convenience of storing remotely media files downloaded from iTunes and can share these files through a large array of devices. The iCloud services are compatible with iPhone 4S, iPhone 4 and 3GS, as well as with iPad, iPad 2 and recent iPod touch models.
When he announced iCloud's landmark achievement, Tim Cook also stated that it is at the heart of Apple's "strategy for the next decade"; so we can expect it to be integrated with more devices (the upcoming Apple TV for example) with new features and upgrades in the years to come.
