Good in theory... Chat feature are unreliable, and have been a problem for me and everyone I know using them. Sometimes messages just won't go through with chat features enabled. Also have gotten weird messages about encryption and not gotten the message. Also very frustrating that Google doesn't use their own beta program correctly.... You will often be last to get a new feature in the beta program. Love the ideas, best chance Android had at competing with iMessage, but they are blowing it.
