I have the excellent book "Maximum Entertainment," which I strongly encourage any serious performer to buy; it has improved my entertainment value for my audiences by 1000% in my opinion. I'll stop what could be a long tangent and get to the point. In the book he talks about the Virtual Soundman 7. This is a device which you carry on your person in order to control your mp3 player or minidisc player. I haven't bought one yet but was wondering if anyone has one; if so could you please tell me what your opinion is of it?
