Some people are asking why bother, but for me it's starting to replace phonecalls it's really nice and quick, simple and robust it even seems to handle transferring from WiFi to data pretty well something conventional WiFi calling doesn't right now.
I don't video chat very often, but when I do, I used to use Hangouts. Now, I use Duo. It's fast. It's simple...no, EXTREMELY simple. And, the quality is perfect.
Now... we just need Allo to officially launch.
