CES always begins on a note of chaos and near panic. You wonder how you'll actually find anything in the convention center maze, but as the day wears on and your lit bag and camera memory fills up, you feel better. But it's not always smooth sailing. Many of the larger booths seem to be peopled by a mass of ill-informed suits who only have their own little area of expertise, and it's seldom technical (and it's also never the area you're asking about). But you can usually piece together something useful with a little digging.- TJN
