There should be a desktop gadget for the computer to perform as per the current mood. There should be mood options like- happy, ecstatic, sad, depressed, angry, etc (but limited upto like, 10) and the computer's appearance, sounds etc should change accordingly. Like, high brightness, loud volume for happier moods and vice versa. Also, the music list on the netbook could also play according to the mood. Like love songs for romantic mood, or soothing instrumentals for depressed mood, rock for happy and so on.
