Daylight Savings

I'm not sure I get the point of daylight savings time.  I mean, what is the point?  Take away an hour here, add an hour here.  Why don't we keep changing it so we actually have some daylight in the winter.  How's that for an idea.  Even things out a little.  I love the long days in the summer, but hate the short days in the winter.  Can't we squeeze a few more days of sunlight in there somewhere.  But then again, I'm sure there is a good reason for all of it.
