I accepted the hangouts thing but I'm not really sure what it offers over normal SMS. Am I missing some killer feature??
Hangouts SMS is pretty standard as far as I can tell, I dare say there will be some interfacing ability with other Google stuff tho. One good Hangouts feature, if you have front facing camera, you can do video calls with multiple people and share screens with each other. saying that, I've never done it on phones, but it works well on the laptop.
