Google Voice is effectively a dead product, isn't it? Doesn't seem that favorable to me.
We'll see if Google tries to wholly replace it with hangouts. I wouldn't be mad unless it were missing features.
And not in a hacked "if you're with TMo/Sprint, you -might- be able to get an email with the MMS in a format that's not reply-able" (and even that, only recently).
Voice might be dead as a brand; Google's unification of communications trend might mean that the technology and functionality will eventually be merged into Hangouts.
