Always set it to true... or better, just make android:targetSdkVersion >= 4. Having it false is only for compatibility with old apps that were written before there was a concept of density in the APIs. Using this compatibility mode can cause some undesirable artifacts such as text metrics being slightly inconsistent with actual rendering.
