Query: Sole problem is no way to lock it off

Considering the size, cost and convenience, the audio quality is excellent. I've carried it around for interviews for podcasts and they are fine.The iPod scroll wheel can control the recording unit, so a separate start/stop button is not required on the iTalk. Unfortunately it's there, though, and the iPod lock switch does NOT override it. So you cannot keep it assembled and at the ready because it's forever turning itself on and draining the battery, recording hours of unwanted background noise. It's like having a camera that you have to take the film out of after every shot.If the iPod software can be upgraded so the lock switch locks out this button, the utility of the device would be greatly improved.
