No kidding. The integration with Google Hangouts has been a disaster, and me moving to iOS has made it even worse. Of course, there are no good competitors, so I'm stuck in the holding pattern just hoping some of the ridiculous issues get fixed.
GVoice used to have ATROCIOUS call quality that seems to have been ameliorated by Hangouts. Calls within the US and Canada are still free, voicemail service is second to none, and I'm extremely happy with the texting integration with Hangouts. What else do we want?
EDIT: Also, the OSX Hangouts app crashes about every 2 hours with no error message. This is a "known issue" of varying types on Google's site, but customer service with them, well, you know how that is.
It's not necessarily intuitive unless you know to look for it, and it might not work if your Google Contacts are incomplete (as in, you don't associate your Hangouts friend with his phone number). But it works really well for me.
Oh finally, Bob Robot comes up. I click it. It says "Bob Robot isn't on Hangouts right now..." Well I don't want that. I want to send an SMS.
OK let's look for a green chat icon. Nope, just a smile button to put emojis in there.
This is OSX's Chrome plugin as stated.
Why would a company as rich as Google want to be in the domain business? It can't ever be material to them. I wouldn't be surprised if Google abandoned this business and transferred domains to, say, Godaddy.
