Don’t plan on buying Apple’s Powerbook G5 this year. The chip is just too hot (temperature-wise). Apple was clever with the G4 and made the enclosure out of metal, then aluminum. Apparently the G5 would make the aluminum enclosure into a frying pan. Side tip: don’t place a hot frying pan on your lap. And don’t put any valuable computer parts in a hot frying pan. InfoWorld has more.
