MSN Messenger 7.5 - Free Voice Conversations!

I just tried MSN Messenger 7.5.  What can I say?  Amazing.

The Messenger team is cookin'!  Seems like everytime I've installed a new version of MSNIM there's been some useful new feature I've found even if it seems insignificant.

MSNIM 7.5's new feature?  Free voice conversations.  A friend of mine was in Vancouver, British Columbia today when he sent me an invitation to have a voice conversation; I was in Redmond, WA.  In two minutes, I had installed MSNIM 7.5 on my Dell D600 laptop using the built-in microphone and was having a voice chat.  The quality was amazing!!  No echo, no delay, clear audio.  I don't know how they did it but I've got to get my entire contact list to install it.  Awesome.
