Although now my iStat is showing the following: HD: 42 CPU A: 58 Enclosure Base: 38 Enclosure Base2: 38 Enclosure Base3: 36 GPU: 56 GPU Diode: 60 GPU Heatsink: 50 which might seems A LITTLE BIT higher than normal, but I just find that I can't possibly rest my palm on the palm rest to type on my unibody MBP ANYTIME even though I am not doing anything heavy on it. It's relatively hot although it's not burning hot but sweat will starts to form when my palm is on the palm rest for some moment. It seems that it's because the battery is right underneath. Is this normal as compared to what you guys are experiencing? Because it will be kind of weird if the large area of palm rest on the unibody can't be used to rest our palm while typing. Compare to my previous white MB, I never experienced any hotness on the palm rest until this new MBP gives me this kind of feeling, causing me to lift up my hand whenever I want to do any typing on it, which is what I am doing right now writing this. How about everyone of you who own the unibody MBP?
