(yes!) -- Apple used yesterday's WWDC keynote to unveil a slew of changes and updates to OS X, iOS, and the App Store, but no new hardware. Instead, the focus of the event was squarely on developers. Yes, new features like improvements to iMessage, family sharing, and OS X to iOS AirDrop are nice updates for consumers.
