Greetings all. I was thinking about getting a new powerbook. Does anyone here have the new 1.5 combo or the 1.6? 15" I was curious about heat issues and noise issues. Do the new Books have a different CPU that produces less heat. I had one of the last versions and , whew , DID it get HOT! With a 5400 drive, it may get even hotter now. And if the CPU is overclocked then it could get REALLY HOT! ANy information on these new upgrades would be very appreciated. Its seems to me that the 1.5 is the sweet spot in cost etc.
