GrandCentral is finallying becoming Google Voice ( I am sure people are going to be confused with Google Talk and Google Voice).
I would love to see an integration of Google Talk, Google Mail and Google Voice,
- Combined Contact List
- Combined Inbox (GTalk is already integrated)
- All you may need t do is log into Gmail (Gvoice and Gtalk will be just tabs or plug-ins).
- Ability to make and receive phone calls from GTalk/GMail itself
- Gtalk notification when someone sends you SMS or Voice/Mail (Gtalk allows you to send SMS already in USA).
Basically GMail becomes your one stop communication solution.
