It was one of my favourite things about the Hero...the glowing trackball looked so cool...and was easily recognised, unlike the Desire which just has that tiny green light that flashes...BUT the huge flaw with that is that if you are charging your Desire, it glows orange to show its charging but DOESN'T glow green to say you've got s text. So if you're charging and don't notice your text tone (or have it on silent) you wouldn't know you'd got a text.
