I was about to comment about that... I've had one for years and still find clever things to do with it. For example, when searching a project in my editor for a string, turning the knob jumps between search results. It's amazing how much functionality you can eke out of such a simple input device. It's made me consider other purpose-built init devices (like some of the midi controllers mentioned earlier). I have a Native Instruments controller designed for one of their massive sample libraries that I'd love to hack as a general purpose programmer's helper. Anyone have any experience with such devices? What other clever uses of these alternate input devices am I missing out on?
