Making a Drupal website mobile-ready is a big challenge for site designers/developers. On the one hand, you are expected to develop a site that uses the latest tools (AJAX, jQuery, etc.). Then, just when you think you've got the requirements nailed, you see the last line that says, "must accommodate mobile browsers." This, in effect, amounts to having to create two versions of your website: one for current browers and one for browsers circa 1998 with tiny displays.
