Can someone help me get a handle on all this ? I don't really know what Hangouts is ? I pretty much ignored it because it was part of G+, but now it isn't ?
Where does Google Chat fit in this ? Currently I use my GV number as a separate phone number, used on my laptop, not integrated with my cell number much. So I have incoming calls forwarded to Google Chat, not my cell. Chat then rings on my laptop when I have an incoming call.
Does Hangouts replace Chat ?
Also, can I use my Nexus 7 with Hangouts and my GV number to make and receive calls ? Is it going to use my cell minutes even if I'm using my GV number ?
