I no longer compute on a couch, but if you like trackballs, I don't see why you wouldn't like trackballs while sitting on a couch. I used to be able to find somewhere to set it, and it was better than using the trackpad.

But if you like trackpads, you might like them more than trackballs. And if you dislike trackballs, you might dislike them more than trackpads.

Trackballs never disappeared, although they're not mainstream anymore; you used to be able to get a trackball to clip to the side of your laptop, or get a laptop with a built in trackball... But times have changed.
