Why isn't robusta coffee more popular?

Most people feel that robusta lacks the flavor that arabica beans possess.

Also, robusta is harder to grow because it needs more rainfall and warmer temperatures, thus limiting where it can grow. 

However, robusta coffee is catching on because of its high caffeine content and is the secret behind Death Wish Coffee, a highly caffeinated popular coffee.
