Really? (and I'm referring to the Android platform if this wasn't made clear, just a heads up)
Let's take a look at the videos:

I actually do find some Droid commercials to be interesting in that they're similar to those you'd find in action movies, and they're pretty good. But that's besides the point, because they definitely depict their phones/tablets as machines (which they are of course, but clearly in a more "robotic" sense for lack of a better word), and even depict their users in the same way. Maybe some people enjoy the idea of being robotic, which is why I stated it unsurprising that the Android version of Siri would be lifeless and robotic, which fits their philosophy well.
