> winter just doesn't have enough daylight to think you can get everything done with sunlight

That's the perfect way to say it.

The other piece that a lot of people are missing is the whole larks (early risers) vs owls (late risers) divide. I think the best illustration of that is to ask, if you got your pick, which shift you'd take, based solely on your own body and habits: 8-4, 9-5, or 10-6 (or perhaps even further in one direction)? My guess is that the answer to that question predicts your desire for Standard or Daylight time pretty well.
