I didn't cover applets in the book because I don't like them. I think that resources can be better spent in developing a unified deployment architecture for deploying Java/JavaFX apps to Android, iOS, Windows Phone, desktop, and other environments.
Native apps are seen as more performant and have full access to the device. However, it's more challenging to deploy a native app to as many devices as possible, which is the big disadvantage that native apps have when compared to web apps.
To my way of thinking, putting a Java applet into a browser is a bandaid solution to deploying a Java app to as many devices as possible. The developer is faced with deployment difficulties including security headaches. I think Oracle should (and will) create a better deployment solution so that Java/JavaFX apps can be easily deployed onto existing smartphones, tablets, and desktops.
All the best.
