Great webcam, but video-chat is not longer available.

Summary: I have enjoyed using this webcam to Skype with my daughter who is away at college. I was intrigued about using video-chat (w/o Skype) because another review had said how clear it was, and the clarity of the picture has been an issue with an earlier webcam (not by Logitech).
Summary: Very impressed with how easy it was to use this on Skype. Just plugged it in and there it was. I am running Windows 8. The quality difference between my inbuilt camera on my all-in-one desktop, and this Logitech is night and day. I have not tried the built in microphone...
Summary: This is by far the most expensive webcam I have bought, but it is well worth EVERY penny. The video is CRYSTAL CLEAR and the built in microphone is wonderful. I get constant compliments on how clear and clean I sound while on Skype, Ventrilo, Teamspeak, or any of my other VOIP clients.
Summary: I own this c510 and also the new c920. I was surprised to find that the c510 actually has a clearer image (on Skype) than the c920 on Skype, even though the c920 claims 1080p in Skype HD (gimmick).
