I have been thinking about that lately. How I want to talk to my computer to do simple things like go to this web site or play that song. Not as a replacement but as a supplement, where I still use a mouse and keyboard. This allows for me to speak and type at the same time.
I also have been thinking about audio logs where I can keep a daily or whatever log of the happenings in my life. The audio interface plays right into that where I can just say to the computer "Personal Log" and it starts recording.
AMD has been slowly ramping up a drumbeat about their plans for the future of the CPUs. With their recent acquisition of ATI they have a key component for their idea of modular processors. Ars Technica has a good post explaining in depth the multifaceted plan for customizable solutions.
Intel on the other hand seems to be sticking with their general purpose processors by pushing more and more cores and good performance per watt numbers.
