PhoneGap is about marketing, not about software. For customers it's difficult to find a specific website, but it's easier to find an app in the app store. The devs are still web guys, but thought they will sell more if it looks like a "real app".
I disagree. I used PhoneGap to develop my cloud-storage app so that I don't have to develop the App for 4 different platforms (iOS, Android, Windows, BlackBerry). I believe most devs use PhoneGap to develop real apps, not just to pack their existing websites into native apps.
This makes sense, thank you for the insight :) Wouldn't it have worked as a normal website? Does PhoneGap offer access to native APIs that are not available from web?
