I have no problem with that. This a great demonstration of what Apple does best - optimizing products to fit the needs of most users. Google already has the voice tech in place, but often fails to follow through on the usability front. A perennially annoying example for me is when I'm on the road somewhere, bring up Maps, and ask for directions from wherever-I-am to 'home'; it doesn't know where 'home' is. This is even more annoying, because there is a 'home' tag in Maps, but it doesn't get searched on. Likewise, there's no easy way to tell it that one person is my wife, another person is my business partner, a third person is my nemesis and so on.
Apple are leveraging a culture of paying attention to detail to overcome technical handicaps, but it's hard to quantify or A/B test that, and most firms aren't comfortable with a budget line item called 'magic.'
