We're still not entirely sold on the whole voice command thing when it comes to mobile phones (though admittedly it's very helpful while driving). But you've gotta admit Microsoft's Tellme service (whose purchase allowed Windows Mobile to put the old Voice Command out to pasture) looks pretty compelling. Sure, it's a few extra steps to do basic functions, so it's probably not something we'd use while walking down the street. But it absolutely would be handy in a car, and you have to admit the speech-to-text is pretty cool.
