It looks like Dell has learned from the "Dell Hell" incident, and is monitoring blogs for mentions of the company's products. However, it looks like they might be being a trifle too pro-active - this guy had nice things to say about their monitor, and got a message that started with:

Thank you for contacting Dell about your issue. I'm glad to be of assistance. I sense you are not getting optimal performance from your system. I want to help you get it working quickly so you can enjoy your computer.

I think they need to put real people, instead of automated systems, in charge of that monitoring :)
