You have it correct, theoretically, regarding accessibility. Tables
should be used for tabular data, divs for presentation and layout.
However, many people confuse accessibility with consistency; they want a
look-and-feel that works the same no matter what the browser. (Why they
feel this is accessibility is anybody's guess, but I've seen it a number
of times). In this latter arena, on a practical level, tables are
typically your best bet.
I've done a lot of tableless and table-based layouts, and the
unfortunate fact of the matter is it's a lot easier to create a layout
that is consistent cross-browser and cross-platform using tables. Until
IE supports the CSS2 'display: table-*' elements (which is the easiest
way of creating columns of the same height), this will continue to be
the case.
Now, this does not mean you should create a bunch of nested tables for
the layout. I find that a simple skeleton made of a table with a few
columns can create the basic page layout, and then I use as much CSS as
I can within (unordered lists for navigation menus, floats to position
image/caption pairs, etc.). This combines some of the best of both
worlds, and creates a fairly accessible page at the same time.
As in all things, it's a matter of balance.
