Just FYI, if you are a runner, and like myself want a metronome to help keep your cadence, I would recommend this little product: Crystal Metronome. It’s a very simple little app that lets you set a beats per minute (bpm) rate. You can then output it to an MP3, drop it on your very small MP3 player/IPod, and set it to repeat. For running I set it to 180 bpm. You can also select from some different sounds for the beats like a high-hat or wood block. A lot of Pose or Chi runners will use these little clip-on...
