...of the nasty heat. My 12" gets scorching hot on my lap, and is very uncomfortable on my wrists. The fan runs half the time when I'm just browsing Macrumors, or checking email or using iChat. And forget about using XPlane, the fan runs at full speed and the small area above the keyboard gets so hot I can't even touch it. I worry the freakin thing is going to catch on fire. I miss my iBook G4 933, which ran much cooler. Do you all think I should do it? Any new 14" owners out there can comment on heat issues with your new machines?
