I haven't seen this discussed here before... I absolutely love the invisible shield on my ipod nano. A little hard to apply, but a wonderful product. Well, the same people offer laptop invisible shields. I'm tempted. I'm super-anal about keeping my computers nice, and my experience with the shield on my ipod tells me that nothing will protect my macbook for its life like an invisible shield. But my concern is heat. My macbook doesn't get very hot, but I'm worried that putting this shield on it would trap too much heat and it would get really hot, perhaps even so hot it would be bad for the laptop. Has anyone done this before? Does anyone have any thoughts about the heat issue? thanks!
