> What does the customizable firmware get me? I've never considered "layers" on a pointing device, like a keyboard. I could see it as useful; although maybe not with these trackball designs. I'm not sure what form factor you'd want for layers. But, I could see stuff like "go desktop left/right", "prev/next tab", "skip video forward/back", "volume up/down" as things which it'd be neat to while casually using a computer, without needing hand on the keyboard.
