Incredible buzz everywhere about Google Talk… So, I couldn’t decently avoid to test it ;-)

Google Talk is a downloadable Windows application that offers:

• Free calls over your computer anytime, from anywhere, and for as long as you want
• A simple and intuitive user interface for sending instant messages or making calls–no clutter, pop-ups or ads
• Superior voice quality through just a microphone and computer speaker
• A shared Gmail contacts list that updates automatically with the people you communicate with most often
