Everyone and his dog wants a webcam at the moment of course, but I'm in no particular hurry as I don't know anybody, apart from my daughter, who does Skype. Once the stocks are back up in the online stores I plan to buy a decent quality webcam and have plumped for the Logitech C920s. This is very definitely out of stock everywhere at the moment, but the previous version - C920 - appears to be fairly freely available. I've tried to run a comparison of the two units but so far I have only seen mention of the privacy cover on the C920s as the main difference. Surely all you need to do is disconnect the webcam by removing the USB plug when you're not using it. Apart from that, HD image quality, streaming rate, stereo microphones, automatic focusing and light control seem to be common to both variants. Has anyone here had any experience of either or both webcams, or would care to clarify what they perceive as the principal differences between the C920 and the C920s?
