all the acknowledge about Tv and sound system are from my father and my uncle.....
they spent a lot on that.....
they even disucuss the most advanced speakers or Blueray players that i have no idea of them.
i think the point is target customers.
for other product categories, some rich people probably do not understand that much about the car compared to people who love cars, for example. They may think a car is just a car, and they don't need luxury car, but just safe and comfortable....
So for your elder relatives, they just are not the person who like IT products more than other people....
To be honest.. sometime i also feel sick of my dad....
he rather drive a FORD, but spent a lot on his HIVI
