itwbennett writes "The trouble with Google Voice is that the way we use phones has changed — and it hasn't kept up with the times: 'Fewer people have a mobile phone and a business line and a home line that might make One Number For All so. 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."
I've been very happy with Google Voice for a few years now, and one reason is the transcribed voice messages, which may get hilariously garbled sometimes, but are almost always correct enough to be useful.
