HTC Hero :: Does Anyone Actually Use Trackball / Need Apps Or Games ?

I've had my hero for several weeks now, and i've barely used the trackball at all; once or twice for fine tuning the cursor position (functionality that could easily be replicated by a couple of cursor softkeys) and when using the camera (which is only because they *make* you use the trackball).
I wouldn't be surprised if we start to see android phones released in the near future without the trackball.

I wouldn't mind, but i searched the app store and i couldn't find a marble madness clone anywhere! Does anyone use the thing on a regular basis or find it indispensable in any other way? Any good apps or games that make use of it?

While I'm at it - i dont think i've EVER pressed the call button (furthest one on the left), always use the touchscreen instead. I just pressed it now for the first time to see what it would do, and accidentally dialed somebody, they just called me back to see what i wanted, because all they could hear was the clacking of keys as i typed this post.
