The only problem I ever had with tables being used for things other than tabular data was strictly from an accessibility POV. I had 2 blind roommates in college and helped set up their screen readers. It was nearly impossible for the readers to follow the page so when it was outputting audio it just sounded ridiculous. So much so that my roommates just gave up on their computers and and would take their assignments into some office to have student aids type them up for them and to help them do online research when I wasnt available. Switching sites to tableless css design helped immensely. I dont know if things have changed but that would be my reason against table design, pure accessibility.
