Mashable recently published an HOW TO: Optimize for Mobile. They list a couple create tools that any good Drupal dev should be using if they have a mobile audiences.

But specifically, their fifth step is to use your CMS, with examples of WordPress and Drupal. Specifically they mention Mobile Tools proving they spent a least a little in researching this (or they have quick access to some Drupal talent). I have used Mobile Tools on a a few sites and it definitely a good way to go to present different displays of a website based on the mobile device. With include integration with WURFL for device detection, Mobile Tools is great.

Always glad to just stumble across references to Drupal in general technology based articles.
