One aspect of Drupal that I really have been impressed with is theming. Drupal makes it incredibly easy to take a static HTML file and turn it into a Drupal Theme template. In fact it is possible to even use some of the HTML/CSS template sites to purchase the template files, and turn it into a Drupal template in no time. All it takes is some getting used to and it can take only a few hours to get a template up and running.
