That would be interesting to see. Isn't the pressure touch on the 6s the same thing as a long press on Android?
It's a little OT... but no, it's not. Because it's measuring force, and not time, you can press for the same amount of time, but the deeper into the device you press, the more actions that are revealed. To my understanding, press a little, it's a tap. A little harder, you can get a context menu (like the long press in Android). Harder yet, you "peek" at the content (this may exist when there isn't a context menu, I don't have a 6s), and finally the POP, you press harder through the peek, and the app, or message, or whatever pops open.
A good example is going through your email inbox, you peek at the messages to get more info, and from there you can delete them while still peeking, or press harder to pop the email open. /OT
On the Apple Watch, ForceTouch (same basic tech, slightly different interactions at this time), you press into the watch to get at background things, like changing faces, pausing workouts, clearing notifications, etc.
