> They want "computer, plan my next vacation to XYZ for me" to lay out a full itinerary and offer to buy the tickets and make the reservations.

Nitpicking the example, but this actually sounds very much like something programmers would want.

Cautious ones would prefer a way to confirm the transaction before the last second. But IMO that goes for anyone, not just programmers.

Also I get the feeling the interest in "computers" is 50/50 for developers. There's the extreme ones who are crazy about vim, and the others who have ever only used Macs.
