Chrome apps are coming to Android and iOS
Google has announced that they are releasing for developers a preview of a toolchain based on Apache Cordova. So what is Apache Cordova? It's a platform for building native mobile applications using HTML, CSS and JavaScript.
So, why is this good and why is this bad. The good will be cross development for Chrome apps, Android, and iOS. The bad will be having a flood of ported apps that don't fit the screen correctly and developers not caring. Think of a phone app being used on the tablet for Android.
