I'm not quite ready to "throw the baby out with the bathwater" as we like to say. Emulation is fine as long as it *fast enough*. That it can be "faster" isn't particularly important as long as, as Barton points out, the economics of getting from "too slow" to "fast enough" makes sense. I think it's safe to say that native performance will always be faster, but faster isn't always the goal (sometimes it is).
