A quality-minded pervert would probably just buy a $150 digital point-n-shoot. Just as many megapixels, no shutter sound, and much better optical components.

and people in the train will see you with a digital camera instead of a multi-use device like a phone.

A technical pervert would take a HD video with their phone and then use multiple frames to mathematically extract even higher-resolution stills from it:

Let's hope to God people on Hacker News don't start taking upskirt shots.

They would get in arguments about the latest up-sampling frameworks and never ship anything.
