Speaking from experience as somebody who has done this sort of trip: Yes, it's hugely useful and there is a real business benefit. First off, we're probably talking about a time when there were only a few direct flights a day from SFO to the relevant airport so if he didn't go that afternoon he'd have to wait until the next morning so instead of flying through the night he'd be flying through the day - flying RIGHT T…

What Apple doesn't do is float trial balloons just to have something to show. Lot of companies will mock up some design that is approximately similar to the expected final product and show/announce that, then finish figuring out how to build it. Apple's ideal is to make a big splash by showing something unexpected that you can buy in the very very near future so people run out and buy it, garnering additional publicity based on the big lines and big numbers of customers.
Which is great if you can pull it off, though it seems inevitable that one of these days they'll guess wrong. If and when they do blow it, it'll be at least a billion-dollar mistake to have built up so much inventory in advance of finding out whether people like the thing.
