I've seen some posts, on some blogs, about the SMC firmware upgrade that Apple released this week. I installed it, so whatever has been written about it, I should be able to check. TUAW and others write that the upgrade causes the MacBook Pro to run cooler.
Well, I still think it's a bit hot at times, but yes, it is cooler. Not very much, but I think it's just enough to make it slightly more comfortable. So thanks, Apple, for the upgrade.
