I also wrote about a few other ways of adding classes to post_class on problogdesign a while ago. It's a really useful way of fine grain styling. http://www.problogdesign.com/wordpress/styling-different-posts-in-different-ways-with-post_class/ I think you’re right with what you say about knowing the category names, and to be honest, I think people know their category names more than they know their ID’s, but a useful concept non the less.

function category_in_post_class($classes)
{
global $post;
foreach((get_the_category($post->ID)) as $category)
$classes [] = 'cat-' . $category->cat_ID;
return $classes;
}
add_filter('post_class', 'category_in_post_class');
