Ask HN: How much money have you made with a single personal laptop?

I have a 2015 MacBook Pro and I've made in the ballpark of $75,0000 or so with it from various income streams. (I've made more with a corporate one but I think that's less interesting than the personal laptop!)

Surely someone on HN has become a millionaire with a single personal laptop. I wonder if anyone has ever became a billionaire?
