	Hmm, I disagree.  For certain purposes it can be real nice to have access to a processor that can handle "real-time" processing.  No matter how fast CPU's get they still use Operating Systems which interupt tasks whenever they want.  Sometimes you *HAVE* to know that a loop is going to take 250us.

	Now, if CPU's get so cheap that they can throw a couple into a box and the silicon designers provide ways to invalidate pipelines and anything else that can screw up timing.  Maybe we will see the DSPosaurs fall into the tar pits.
