Yeah, he does that on the day he is shipping the device that represents the direction in which the entire industry is heading, the device that is the harbinger of the post-what era in question.
The iPad 2 isn't shipping yet (it begins on march 11). So it would be more accurate to say that he does so when he's really close to shipping it, not on the day he is shipping it.
And yet curiously people don't doubt that he's going to ship it.
