It’s a known fact that Apple is the obsessive-compulsive poster child of the computer world. But their disorder is our gain. Case in point: the upcoming iOS 6, a polished refinement of the existing mobile interface. Among the hundreds of new features is this smile-inducing gem: the reflection on the volume slider actually changes as you angle the phone (it uses your iPhone’s acceleromter to pull this off). Pointless? Perhaps. But I love it.
