The worst thing is that the farther north you go, the less it matters. In Ireland, DST only really makes a difference for a month or so around the change. In the summer, light. In the winter, dark.
DST mostly matters between about 35-50 degrees latitude. Less than that and the days are similar enough in length throughout the year that it doesn't really make sense to change clocks. And, as you say, much further north (or south) you have more light than you know what to do with in the summer and you're probably largely in darkness outside of work hours in the winter whatever fiddling you do.
