Regarding F.lux I don't think automatically adjusting the brightness or screen colour according to the time of day would be much help. It would really depend on the light of the room you are in. It would be better if your computer or laptop had some sort of built-in light sensor and the software adjusts the screen brightness and colour according the light in the room.
If anyone is looking for a really good 1TB hard-drive get a Buffalo MiniStation HD-PCU2. Got one recently and they are the shizz.
