Heat. Apple?
It's rarely a day that passes without "news" about how hot the MacBooks (Pro included) get. When Apple releaed the MBP in January, we heard of quick revisions, of firmware updates fixing stuff etc. - however we have yet to see a firmware update for the MacBook.
What truly gets me... The intel core duo processor in my MacBook can scale between 1.0 and 1.83 GHz. Yet I've only very rarely seen CoreDuoTemp showing the 1.0 GHz number. Smirkingly, some might say that CoreDuoTemp probably actively hinders the processor to go below 1.33 GHz, but I doubt that. Yet: Even when I'm only using my MacBook in a café to write a few articles in TextEdit, quite often I find the cores running at 1.67 or 1.83 GHz. They _do_ go down to 1.5 and sometimes 1.33 GHz, but I only see 1 GHz when the screen goes dark and I wake it up again. Then, for a fraction of a second, it sometimes shows that number.
What I really, really want is an Energy Saver setting that lets me set that machine to the lowest possible setting. I mean: I want to restrict it to using _one_ core running at _one_ Gigahertz. It's surely enough for TextEdit, right? (At least as far as I remember, I _did_ write stories even in Mac OS X Public Beta on my 300 MHz blueberry iBook, so...) I'd actually *bet* that my MacBook could let me write more than 6 or even 7 hours if I could restrict it that way. Is there any *real* reason Apple doesn't allow such a setting? Anyone got such a reason? - posted by Patrick Armbruster @ 01:53 [article link]

I like your idea. It makes me think of some of the new automobiles that are able to run on 4 cylinders when cruising down the highway and then kick in to all 8 cylinders when you hit the gas. Wouldn't be nice if a MB could do that?
You can use CHUD. Like I mentioned in the article. But only to turn off one core. But I really, really mean that Apple should make things easy in Energy Saver to control this...
