Excluding the “read more” from specific categories…

I posted a topic a while back about a one category exception to a rule on the homepage of my blog. Well…the point was that I wanted to show a whole post for a specific category, and the truncated post for all other categories. I was successful with this code:

<?php if (in_category('pages')) {
                  global $more;
                  $more = 1;
                  the_content();
                  } else truncate_post(410, ""); ?>

                <a href="<?php the_permalink() ?>" rel="bookmark" class="readmore" title="Permanent Link to <?php the_title(); ?>">
    read more
    </a>

Now…because I am showing the whole post on the category “pages”, I have no need to have the “readmore” link on those posts. Conversely, I do want to keep the readmore for the posts that have been truncated.

So my question is, how do I include the absence of the “readmore” link from the “pages” category, but have it function as usual for all other categories? Should I create another if/else, or can I simply include it in the existing code somehow?
