Which phone will have the option to phone to pc calling?

I voice chat with my friends over gtalk everyday.

I want such a phone so that it allows me to use gtalk inside the phone and allow me to call other online gtalk users .

So that I dont have to sit with my laptop, mic and speaker, (no my laptop has nothing inbuilt)

I want to move around and voice chat on gtalk, even while outside.

I am Tmobile user and was planning to upgrade my phone.

I pretty much agree with you.
