I liked your perspective on the first 2 points but the 3rd one made no sense especially as a "knock out blow". Drupal has MODULES and WordPress has PLUGINS. And the knock out blow from my perspective is most Drupal Modules are built as code-only monsters useful only to ubergeeks, while WP Plugins are often actually useful and usable right out of the box. I wish this was not the case, but as you mentioned before Drupal theming is so complex that most module developers just don't address theming at all and the result is you ad a Drupal module and it looks like puke on a page. WP in contrast you have a good balance of functionality, theming and usability in a lot of the plugins available. Drupal still has its place though, but its theming system is so bad it is actually shooting itself in the foot and it affects not just theming layer but even the module development.
