So at this point I stay away from the nitty gritty of the native coding for iOS (Objective C) and Android (Java) neither of which I have had much experience with or interest in. I will continue to use PHP for web host and services. WordPress will continue to be my choice for a Content Management System.
I have discovered Netbeans 7.3 support for HTML5 that is coupled to the Chrome browser for development. Having used Netbeans for sometime and my browser preference being Chrome this transition and learning curve looks to be an easy one. The other major new component is jQuery Mobile which will round out the tool set.
The major difference I see between mobile and traditional web design and development is that the eye candy gives away to an intuitive and action oriented focus. With limited real estate it is essential to deliver results with fewer actions and to transition pages logically, intuitively and smoothly.
Next step is to determine an app that I am interested in doing that has some meaning.
