My ds has been a gadget baby since he was 6 months old. Guess its the boy thing. But I was shocked to see him operate on the new dvd cum music system this morning.  Guess  the touch screen and remote helped. But how did he know about the cassette player and how to open and insert the casette? It certainly sounds interesting but, looks like my new music system won't last long. How to discourage him from touching it further?
