I am evaluating open-source CMS systems to see which one(s) would be the best option to deliver rich mobile web based applications for mobile handhelds.
So far I am leaning towards Drupal because it seems to be the most extensible, flexible, best performance (cache & compression, etc) and has a good user management system.
The CMS must be able to deliver HTML content that is ideally rendered for most smart handheld phones. I have to assume most if not all would do so as you would just control the front-end (headers, CSS, HTML and javascript) to ensure it renders correctly...correct?
So, it Drupal a good option? And, is there anything else I am missing when choosing a CMS to deliver mobile web pages?
