Acceleration is actually useful for both. If you're running in a constrained, mobile or sensor environment, then you really do want acceleration that improves your power efficiency. It's also useful if you do high volume serving, but that's obviously not the case here. (For example, Google's voice recognition on Android can run when offline.)
