Some new Dell XPS series have an S/PDIF (optical) output along with the headphone out, you just need an adapter.
I am sure there are others, I've noticed a few new laptops with S/PDIF printed in the plastic (or metal) next to the headphone out, so probably most are using the same technology built into some particular brands and models of audio cards.
