Just wondering if anyone has noticed that when the machine is under load the power supply gets very very hot. I am exporting a 720p film in iMovie [taking about an hour for a 35 minute film] touching the MacBooks power supply I found it was almost too hot to touch. The room I am in is 24 degrees Celsius and the power supply has plenty of room around it for ventilation. Now I know iMovie is still not optimised for 64bit neither is Final Cut Pro, I've observed that both are only using about 25% of available CPU. I'm a bit concerned that the power supply will explode into a million pieces when trying to use future 64bit versions of FCP and iMovie, as i primarily bought this laptop as a video editing machine [and please don't tell me to buy a Mac Pro, I need portability]
