Ever since I watched Scotty attempt to work with the Mac computer in Start Trek IV: The Voyage Home, I have always wanted to interact with my computer via voice commands. If you don’t know what I am talking about, you can view the clip above (the relevant part begins at the 1:05 mark).  The latest version of Yahoo! Go for mobile devices finally gets me there in a very useful manner.  This application allows you to input your search terms via the microphone on your mobile device.  The voice recognition is quite good, and it saves quite a bit of typing time.
