Verbatim? I just tried two off the top of my head. "Hey Siri, how do you spell cantaloupe?" and "Hey Siri, how tall is mount everest?" The replies were "The answer is cantaloupe" with an on-screen definition and "I've found an article on Wikipedia about that. Shall I read it?" In neither case were the answers succinct and on point as in the Echo ad.
Of course, that assume it will actually work as advertise. Also, unless I'm mistaken, "Hey Siri" requires your phone be plugged in. My phone is never plugged in unless I'm turning in for the night. I realize Echo has to be plugged in as well, but that is it's natural state, having my iPhone plugged in is not.
