It's important to distinguish between PhoneGap's performance, and the performance of jQuery mobile or Sencha Touch, which are more responsible for the native sliding and scroll features of the non-native apps. In my experience with PhoneGap, the framework does a great job of exposing native features of the iPhone, i.e. recording audio, taking pictures. The downside for me came only came when adding the visual effects to mimic a native iPhone app. Trying to fix all of the quirks with jQuery mobile, such as persistent headers and footers (although the latest RC has been looking much better), has ultimately led to my abandonment of the non-native app.
