When you compare an analog ignition to a digital system, it's easy to see that the new digital ignitions are physically smaller, and can have more internal features. Since there are so many good things associated with digital ignitions, does this mean analog systems are obsolete? Hardly. There are plenty of high-powered, sophisticated ignition systems out there that get the job done (some with flame-thrower-like spark capability). The MSD 7AL3 on the right is one of them.
