I have a 2009 Ford Focus. I installed the aftermarket Sync kit from the Ford parts department. Does it come close to the voice input on Star Trek TOS? Absolutely not. Does it save me having to push a crapload of buttons if I want to change inputs? Yes. Does it make talking on the phone safer and easier? Yes. For example: Using voice controls: I am listening to the radio. I decide that I would like to listen to Weezer. I press the voice button and say: "USB" I press the voice button again and say: "Play artist Weezer" Outcome: I never take my eyes off the road, I'm listening to the music that i want and it took all of about 5 seconds to accomplish. Using radio knobs: I am listening to the radio. I decide that I would like to listen to Weezer. I press the Aux button. I press the Menu button. I turn the dial to Artist. I press the enter button. I turn the dial to the alphabetical group that has artists that start with W. (There are three alphabetical groups) I turn the dial a lot more to find Weezer. I press enter. I turn the dial to All Albums. I press enter. But I guess you're right, voice input is way more inefficient.

New Raspberry Pi's have an included subset of instructions that when powered up send a message to all of your elected representatives telling them that you're against Obamacare, posts to liberal media sites about how evolution is made up and submits a profile to eharmony for you!

Habitual drunk driver is found in his car, with the keys, drunk.... How about we enact a law to get rid of stupid people. That would make me happy.
