As most users, I am very impressed with the video quality and the experience. I had a video chat with a my friend in Japan and let me say that I was able to notice much more of her face today than I did before. She was also able to clearly show me the details of her new apartment using a wireless webcam. The other features, IM, Voice were pleasant experiences with the new UI. Good Job Skype!
