Yeah, I don't think so...at least not yet. There's not a good, solid alternative replacement just yet. True, they're touchpads and eraser heads on laptops, but it doesn't give the same precision as a mouse.
It pointed out the Guitar Hero guitar, and you could look at the Wii's remote, but they still suffer the same problem in the precision department, and in the case of the GH guitar, it's not suited for the task.
