Not a surprise really.
A completely unrelated issue, but it is like converting the world over to electric cars when everyone has been accustom to petrol for so long. Some people are open to new things and freely buy into them. Some people aren't aware of them. Some people fear buying into them because they do not know enough about them. But most see no point in spending the money yet because what they have right now is perfectly fine and will wait until it is absolutely necessary to make the transition before they do.
