Deciding approach for mobile web development

I am trying to figure out the best/easiest approach to start (and learn) mobile application development. It seems instead of choosing to go iphone or android native app, HTML 5 may be the better approach. Also this will probably allow easier migration to google tv and other devices in the future.
I am considering the following stack:

• LAMP + Zend - Familiar technologies, easy to deploy
• With presentation using JQuery/JQTouch/HTML 5 - cross platform, looks like native applications

Now to start trying it out...
