It's day two of the 2002 international Consumer Electronics Show, and I'm wired and exhausted. I've been sharing the Las Vegas Convention Center with 110,000 people from around the world, and it feels like I've bumped into every single one of them. It's the same thing every year, yet I always come back, for this is the only place you can get a peek at the latest stereos, TVs, PDAs, phones, and other devices about to hit the market.
