Google seems to be really on its way to revolutionize the way we communicate in future. Just look at the products: Gmail with built-in features like docs etc, Voice, social media like Wave, now Buzz. And yes, the Google phone. But what do we really need for future info exchange? I would prioritize four things:
1. Data transfer speed at cheaper rates
2. Reduced file size (with hi-def videos storable in bytes!)
3. Longer battery power in all gadgets
4. Inter-compatibility

Go Google go :)
