To what end? What specific value add is a multicore processor to mom and pop that is not being addressed by an intel quad core? The only thing that moves units is applications. As far as the general user is concerned, the processor does not exist. And that is how it should be.
Are you kidding me? Once cheap massive parallelism becomes the norm, you're going to see amazing applications for the average person, especially intelligent programs. For examples, intelligent answering systems, voice recognition, handwriting recognition, face recognition, dog walker, housekeeping robots, portable language translators, self-driving vehicles, sentries, etc... The possibilities are endless.
