We're getting one step closer to tables again. One day people will realize that all the extra effort in doing this in CSS is worthless and just use tables. Who cares that your layout is made with tables instead of divs? Mixing presentation with content? We already have a much better solution for that, it's called server side templates. Just use what requires the least amount of work, for some things that will be CSS for other things that will be tables. Don't get hung up in cargo cult design.
