1. Write native app's for both the platforms, pay once and cry once. 2. Write web mobile apps, realize how sub par the experience is, rewrite in native. Pay twice, loose competitive advantage, and cry twice.
This is what, 3rd or 4th iteration of web app's are going to take over mobile cycle?. My first instinct about any blog that promotes this turd is, either their business depends on selling this solution or the person is huge web guy and never really worked on complex native apps.
