Blackberry, Trendsetter or Needs ?

In my country (Indonesia), Blackberry is very BOOMING! Almost every people dreams to have it because some important people, artist and government also use Blackberry as their device. And now, there is a simple question about this moment. Blackberry, Trendsetter or Needs ?

For your information, Indonesia is a growth country and I think Blackberry booming is just a trendsetter for a few months or years.
