How are you liking the touchpad, speaker, and lightbar on the DS4

They are all minor gimmicks, but all can be really nice if used properly.
The speaker is really cool like in Knack, Resogun, Dead Nation but I rarely use it, cause like Dd_Bwest, I mostly game with my smartphone headset plugged in (the jack input is the best thing about DS4 actually).
Touchpad has potential to be nicely used in weapon swapping, may act like 5 additional buttons by swaping and clicking, and can be the primary way of browsing in the internet browser and OS in general but Sony needs to finally freaking patch it (should have been day 1)
The light is used in a nice way in Outlast and Tomb Raider from what I heard and is used as a tracking device in the Playstation Eye camera games, so it's important. We totally should have an option to dim, or turn it off if the game doesn't actively require it, though. I sometimes use it like a torch when my room is dark lol so there's also that.
