Virtual Scroll Wheel
Christopher Fahey (via John Gruber):
For scrolling through menus and adjusting volume, the iPhone’s new UI methods are, IMHO, superior to the old iPod’s wheel. But the “jog dial” is still the ideal user interface for arbitrary positioning the playhead in audio and video tracks. It’s a hardware solution that has been in professional and consumer use for decades.
And the iPhone and iPod Touch are totally capable of doing it.
