Oh, thank goodness. Read up on Marie's MacBook Pro update if you want to know what other new and upgunned goodies Apple packed into that gleaming notebook casing, but for now, let us focus on the one update that matters: why the MacBook won't burn your lap (for the most part).

Jason O'Grady reveals in The Apple Core blogs that he left his 2.33GHz MacBook Pro four hours straight, and its temp hasn't gone higher than 122º Fahrenheit (50 on the Celsius scale), according to the CoreDuoTemp monitoring homebrew. That's 40 degrees F (4.4º C) cooler than the hottest his old 2.0GHz Core Duo MacBook Pro got, about a scorching 162º F (72.2º C)! On average, the new MacBook Pro ran at about 115º F (46.1º C).

Jason noticed that the internal fans in his MacBook would run more often than he was used to hearing from his old one. He's betting that Apple made a major adjustment to the System Management Controller (SMC) firmware that controls the notebook's power and cooling functions.

There were a couple of skeptical comments to Jason's post. One, in particular, was betting that all this constant running on the fans would cause the fans to wear out faster (Hope that still falls under the warranty). Then again, heat was a major complaint among MacBook owners, and this could be Cupertino's way of saying "we're sorry?" If any of you guys have gotten your new MacBook Pros, tell us: are they no longer among the hottest items around?
