I think I understand why Google doesn't do it. They're relatively comfortable with the telephony status quo. Via Chrome on the desktop and Android on mobile, they've ensured that no one is in a position to "deal out" their services on any connected device, mobile or not. At this point, Google has little to gain (and much to lose) by antagonizing operators with a serious IP telephony play, especially since any mobile component would still depend on the data networks of the incumbent carriers. It's worth noting that Google is making a move in an area where they aren't as content - home internet access. What I can't understand is why Microsoft doesn't do it. Unlike Google, they clearly aren't satisfied with the status quo and, now that they've acquired Skype, they also have a better starting position than Google does. I keep thinking Microsoft should launch a SkypePhone, but, so far, they haven't.
