That's kind of old world thinking, it's been bugging me. In traditional programming and processor architectures that statement would be true. But if it were true today then Google wouldn't have built the Dalvik and then ART layer into the OS. They'd be compiling them on the developers PC and you'd end up with a fully static App.

The VM approach allows the VM to synchronise application wake-ups which can increase battery life.

Google chrome on Android is acting much like a VM to developers and I'm willing to bet the Android Chrome team are spending a much time as the Java runtime team are on optimising.
