I read with interest the blog update from http://googlesystem.blogspot.com/ about soon to be released the GrandCentral 2.0 service. I liked GrandCentral's services long before Google acquired them. I also hope that once out of beta this service will become available outside USA. I think Google search on voice mail, web widgets and 1 click calling straight from the browser on your mobile phone together with 4G mobile VoIP will finally dramtically change what you consider a "phone" to be.
