Don't have the link, but I once read a study analyzing the Asian market regarding electronics. The focus was on washing machines, fridges, etc. They discovered that more features, even if useless, improves sales.
So you'll have a washing machine with 50 buttons, 20 lights, 2 LED screens. People will buy that over any simpler one.
As long as we consumers behave like this, the other companies go out of business.
