Let.s face it, if you use GoogleVoice like I do, you have the benefit of a very reliable, easy to use, one number solution with voice mail, message transcription, with an elegant call back solution that offers convenience and capabilities not currently offered by any on the US local carriers or mobile operators in one complete package. So I found the Randy Stross penned story in today's New York Times very thought provoking.
To get all the features that GoogleVoice offers one would need Comunikate, PhoneTag and a subsidy by some service provider, as the calls made via the Google Voice application that end up on a landline or to Gizmo's softphone are really free (other than the cost of access to a network) so in essence GoogleVoice is democratizing voice serrvices, and at the same time taking potential revenues away from others who don't offer all of the functions in one place.
As a public service, subsidized by ad revenue, GoogleVoice makes thins easy for people to get services that otherwise would need to come from many different service providers, and not all work well together.
Honestly, GoogleVoice, now with SMS would be worth paying for,if for no other reason than to shut the door on these types of issues between operators and the FCC so they all can get on with bigger issues, like making broadband available to all.
