Text message costs (which are actually close to nothing) are almost always bundled into contract costs. Automatic voice transcription, while still a mean feat, is no longer such a magic trick,' writes Kevin Purdy in a blog post explaining why he's breaking up with Google Voice. The main problem is that, despite some very cool features, Google Voice doesn't play well with others — even apps in its own family. And it doesn't look as though that's going to get better anytime soon.
