Nobody is talking about always. But in general it seems a good enough approach. Hell, many of the AC/BAT switches in todays power management crap things are not always right.
Do I want it to dim the LCD further when I unplug the laptop -- mostly no, but still it does. And the most annoying one is that it reduces the screen blank time to something near 5 seconds or so.
