Well i once had to do a presentation about barrier-free websites and tables was one of the big no-goes. I showed an example with a text reader and the tables totally messed it up.

BUT i don't mind using tables for designs sometimes. I used them for my latest website too. CSS is cleaner, that's true but
1) i was too lazy this time to use div and told myself "i will replace the tables later on with divs" but that's already some years ago
2) i doubt people who are blind will go to my website and check out my games/art so it doesn't really need to be barrier-free.

Though CSS is a must-have for professional webdesign nowadays and i use it on the most websites i do (for other people).
