Fifteen years ago, Steve Jobs made his last WWDC appearance, looking visibly gaunt but still commanding the stage. The June 6, 2011 event should be remembered for introducing iCloud, but will always be defined as his final Apple keynote. Health concerns had been evident since 2006, with Jobs taking medical leaves and Apple no longer downplaying his condition.

iCloud replaced Apple's disastrous MobileMe, which Jobs had publicly criticized for failing to deliver seamless device integration. "It just works," he claimed, acknowledging MobileMe "wasn't our finest hour." The service aimed to eliminate the need for physical connections between devices, representing Jobs' vision for seamless data synchronization across Apple's ecosystem.

Jobs presented approximately a quarter of the two-hour WWDC 2011 event before stepping away. The following day, he would pitch Apple Park to the Cupertino council, never seeing construction begin. iCloud became one of Jobs' final enduring contributions to Apple, fundamentally changing how users interact with their devices.
