Specs don't make a phone great, the software does. You can't just throw more cores to make things faster/smoother. That's just bad engineering. By separating the contextual and speech cores and still using a dual core, if Motorola can deliver an experience which is smooth and flowing, it'd be a major game changer. And oh, if they get the battery to last longer, that itself is a major boon. One of my gripes about the Nexus 4 was its battery life.
