What options exist for mobile application development?
The general consensus seems to be that many of these frameworks work fine for simple applications, but quickly run into walls, bugs, and fails once things are less than straightforward. If you’re writing a simple application, it probably falls in the mobile web application category and then all you need is a web view. YMMV, but know what you want your application to do before making a choice. Most likely, you have to write a native application for each platform.
