It hasn't been used in mainstream computers but it isn't new. It was used in the Cray 3 (even if only one was ever produced) and that was back in the late 80s and early 90s. They've actually got one of those chips at the Computer History Museum in Mountain View. It is also used in some satellite communication electronics.

Even if it gets continued development and turns out to be technically superior to Silicon on not sure how it will fare. If it is found to be environmentally harmful it could end up restricted under something like ROHS. Anybody know how toxic it is once its in its crystallized form?

Oh, and here is a cool video I came across when I googled for the Cray 3 link. Its Seymour Cray talking about Gallium Arsinide at the 1988 Supercomputing Conference.
