Is it a myth? Seems like every other blog mentions you shouldn't do "anything heavy" because heat sensors will force throttle the cpu. Is this BS? Mine won't arrive for another week, so I can't test this more myself. I did torture test one a bit in the apple store - multiple homebrews compiling things, playing flash videos, etc, and although it got a little warm, I couldn't detect any throttling. Has anyone experienced the New MacBook actually throttling? On a side note, what's the best app to detect throttling? I use iStat menus, but it doesn't seem to keep track of frequency. It seems like Intel's power gadget might be useful, but I couldn't install it in the store due to admin requirements.
