Will Web Development Frameworks replace Native IPhone Programming?
<p>I need help clearing up some questions regarding these several third party dev-support frameworks (e.g. ViXML, Titanium Mobile) which promise iPhone app development at lightning speed using only Javascript and XML, without knowledge of Objective-C.</p>

<h3>Questions</h3>

<ol>
<li><p>Are there any features possible on a regular Xcode development platform that are NOT possible for someone creating an app using these frameworks? </p></li>
<li><p>Is there any real savings in money and time when working with these platforms?</p></li>
</ol>
