I don't know if it "felt like 30" because the task felt boring or because you were concerned about being caught, but if it's the latter then I think you know that it was at _least_ on the far side of "ethical".

Also doesn't seem like you really thought it was totally legal if you left the store that way.
Most people in this thread are addressing the legality/morality of installing an app on all those computers in the Apple Stores, but what about the unauthorized use of all those people's likenesses? I'm not familiar with New York state law, but in a lot of states, you can't use photos of people commercially without their consent.
You make a living from art projects. Maybe you didn't make any money from this art project, so you didn't directly profit from the use of these photos, but I would think a reasonable person would see your online portfolio as an advertisement or promotion of your services.
In the original article you talk about how it should have been alright to take the photos:
> I tried to think of a busy public space full of computers, and the Apple Store seemed so obvious.
Apple Stores are quite clearly not "public space", they are private spaces that they allow most members of the public access to. If the photos were taken with a telephoto lens through the glass walls, they'd be totally in the clear (though IANAL). Still creepy, but legally in the clear.
