Greetings from sunny Shenzhen, just north of Hong Kong. I've spent some time in Asia - at least the tech centers - and have never found a place like this. It's like Blade Runner meets 1990s Prague meets the end of the world. I'm here to report on what's going on here in terms of electronics and how it's changing the way we think about price, cost, and value. It's pretty crazy. Thirty years ago Shenzhen was a rice paddy, a town of about 50,000 souls. Today it is a hive, and a dirty one at that. Smog is a way of life. As the sun goes down over the city, the streets take on an amber cast and the darkness falls quickly. There are no picaresque sunsets here.
