I still design in tables mainly cos it’s faster for me. I spend enough time doing design / development at work so I don’t have much time to exepriment…and if i can’t master it in 5 minutes then I’m afraid it gets relegated for when i have time, which is hardly ever! The only thing that i find with divs is that css lacks vertical control. I still can;t work out how to make footers stay at the bottom of the page with a 3 column layout!
I guess it’s best to design what youre comforatble with. there used to be the asp / php debate, but in the end both get the job done. what matters is the end result, and many good sites which are well high in the serps are done in tables.
