I appreciate your enthusiasm, but I'm sorry to say your assertive "No" doesn't negate the fact that my experience is that CSS-based layouts are very often not cost-effective compared to table-based.

We had 15 people doing slicing all day, every day, 50-60+ hours a week. We weren't all morons. You better believe we figured out what works and what doesn't, and as I said, the switch to CSS-based layouts tripled the time it took to get a site to a client. If you want to believe that everyone in the shop just happened to simultaneously become mentally retarded at the exact time the switch was made, you're free to do so. Personally, I think Occam's razor suggests otherwise.
