The ambient light sensor in U80V is so awesome! I just learned to turn it on by pressing FN+A key.
My room is very dim, so i have set my screen brightness to minimum (by FN+F5) and had the keyboard backlit set to Off (by FN+F3).
When the Sensor is ON, nothing happen to the Screen Brightness, only the keyboard backlit Auto Turn ON to mid level brightness.
Then I switched on my torchlight and pointed it right on top the sensor, the Keyboard Backliit AUTO OFF and the screen gradually grows brighter til maximum, the Touch pad horizontal dotted line also grows much brighter when touched.
In Room temp 26 degree celcius, the U80V has been up and running with light applications such as Firefox, winamp, thunder for 4 hours plus, the heat on the palm rest n keyboard area is almost non-exists. This machine runs very COOL and Quiet. I also touched the left airvent, the warm air that flowing out of it just felt a little bit warm and the air volume felt is just a minimal, very different from another notebook here i.e. the air is actually HOT and stronger flow/higher air volume.
Just a simple description on the User Interface aspects above. Hope it will be of a little help for those who's considering this model.
Overall, I rated this model: Highly Recommended.

Have Fun.
