I Agree.

But you might have missed ;-) a tiny thing in my post, I actually said that whether you could use event-driven was not just the programmer's choice, but really depended on whether your language supported it. So we are on the same page.

At the same time, I want to stress that, if you are using things support event-driven, like Java, you should go ahead use it. It might sounds scary at the beginning, but one should try to utilize the best he can grab. After created your first event listener in Java, you would find it is actually nothing difficult.
