In this part we agree, that's why I said that with good defaults, 
configuration might not be needed.

Just like in the first case, this is about configurations, while both my 
and others mails were about two issues:
- chosing a preset configuration whenver you want
- creating presets

And here I talked about the first. The software might know better what is 
the best to save power, and I might know when it should save power. How 
it does (turning off brightness, setting kernel argument in /proc or 
whayever) is not relevant - that's why Is said should i really know?), 
from the user pov.

I hope this makes clear what I meant.
