User Input error!

I was working on fixing an old computer that had a PS/2 keyboard and mouse, and had a bit of trouble getting it to work. As I was working, I realized that computer input devices really haven't advanced as quickly as the rest of our computers. Computers have gotten faster, monitors have gotten bigger, but our input devices? Wireless is at the top of the list. Why are we still using a keyboard and mouse? Why aren't we talking to our computers!? The XBOX 360 currently has a game called Tom Clancy's Endwar which can be controlled completely by voice commands using the system's wireless headset. I can also issue simple commands to my cell phone when using my Bluetooth headset, like "Call John Doe."

So why are we still using keyboards and mice to control our state-of-the-art computers? I remember my uncle having speech recognition software which let him "type" in a document by speaking to it. It seemed much faster than typing, from what I remember, so why don't we extend this ability to enable us to issue commands to the operating system? I'm sure there are still speech-to-text programs out there, but I want my operating system to hear me issue commands, like "open Firefox Web Browser." The software would have to be built into an operating system, constantly listening for commands. The HAL 9000 from 2001: A Space Odyssey worked well, and that was 1968!

Before I even do the research, it seems that we have the technology to do this; voice recognition is better than ever, and the microphone hardware already exists. What are we waiting for?
