Good thoughts. Personally, I'd like to get rid of the system and just go with the rythem that the earth naturally has. Where I live I can clearly see the sun coming up a little further to the south each day and then, after the solstice, starting north. Makes me think of Stonehenge.
This probably wouldn't be ok for those that work and have to live by the clock, though, so I guess leaving things the way they are with the 'spring ahead, fall back' system may be best. My family hates the dark, dosen't like to come and go unless its sunny.
