This is exactly why so many of my friends and family use Hangouts née Gmail Chat. We can use it in the browser at work just by keeping Gmail open in a tab. No IM applications to install or concerns about whether we're running Windows, OSX, or whatever. Then the conversations follow when you log off whatever desktop or laptop you're on via the mobile app. About half of us use Android so it either comes standard or you…
My lord, why isn't Allo just Hangouts 3? They had an established userbase, a name, a brand, and useful cross-platform tools already. I get the desire to start fresh, but that's a lot of established traction in a very crowded market to just throw away.
I was wondering that too. I honestly suspect some executive in Google's team wanted to have more visibility, team and power.
