Any computer speakers with optical input?

One thing I love about the iPod Hi-Fi is that it has an optical audio input. It sounds incredible with the optical audio from a Mac, Apple TV, or sat TV receiver.

I would love to have that for my Mac's connected speakers because Macs of course have digital optical out.

However, are there any speakers out there, intended for computer use (size and whatnot) that have an digital optical input?

Many thanks.
