What's interesting is that they could probably put a higher power (wattage) processor in there and get linearly better multicore performance. But in doing so, the laptop would no longer get great battery life and it would get hot and loud. It benefits Apple to have achieved a level of single core performance that doesn't require high wattage. They may be able to use this to avoid the tendency of applications to eat up any resources available over time and become more power hungry.
