One of the winning factors of iPhone is the App Store. Palm Pre developers can now submit apps to the App Catalog. It’s not sure how long it takes for Palm to approve it, but it is pretty sure lots of apps will be there very soon. The number of apps may be exploded like the iPhone. Currently, Pre is lack of apps and thus the number of downloads in App Catalog is not that much. If Pre gets enough killer apps like iPhone, it would become the real iPhone killer.
