I want to analyze why always this products are named ”ideal for developing Countries”.
I don�t know if the people who lives in already developed countries realize that the majority waste and energy consume is originated there. So it�s look like that you are focusing not in the main problem, that is to modify your way of life.
I don�t think this idea (although good one) would make any difference until you assume the responsibility. There are 6000 million people in this world, but only 700 localed in USA and Europe consume more than 80%! It worth the time trying to change (south!)people activities while you don�t make a thing in your own houses?

I suppose why we called them ideal for developing countries is not because the developed world is perfect but because they can afford technology even if it is a bit expensive. Cheap but useful and green solutions are good for developing countries as you cannot expect their local economy to support costly solutions. Beyond that there is nothing to read in to it. While you are totally right about changing lifestyle and making sure we are more aware of stuff, this is just the supplement such a conscious change needs. Yes, we do need to change our lifestyle before all this really counts!
