Unfortunately those results don't surprise me. Running CPU full bore on a laptop for extended periods of time is probably one of the rarest scenarios out there for laptops. Even with high end video editing, encoding, compiling and all that, the CPU is working in bursts, and the ramp up and ramp down times are probably enough to let the system keep up with each other. I would be wary for the thermal throttling happening too on the CPU. Once again, apple giving up function for the sake of form. Makes me sad, I really want to keep buying apple products but they keep giving me reasons not to. I'd be OK with the thing being a couple Mm's bigger to make sure it had the internals to not loose steam like you noted.
