This is a great read that you should read. Thanks to Kurt Krejny for giving me the link.
"Tables vs CSS: 15 points to consider when choosing between a traditional table web site and a CSS-P" has a number of very good points. My first experimentations with full on CSS-P have been with the blogs I have created, or helped create. Using CSS-P in this fashion can be a very frustrating experience. Especially when you find out that specific attributes are still not working across the major browsers. While I do not agree with all of it, I do agree with parts of this argument. I have found that I employ a mixture of the two technologies because that is what works in the most possible situations.
The one large grain of salt here is the fact that they are trying to sell their product, but still, even with that, these 15 points are worth reading and thinking about.
