You came to the right place!
I've written a WebRTC Device Cheat Sheet to make it easier for you to understand WHERE and HOW WebRTC will work for you.
In this sheet, you can find the different alternatives you have in each operating system, browser and platform so you can decide properly where to focus your efforts.
Best thing? It is already updated based on Apple's iOS 11 / Safari announcement!
