My wife and I have a mixed marriage. She uses a pc and I use a Mac (OSX 10.4.11). We have made peace with this difference, but we are now faced with a new challenge: With our daughter just off to college, which web cam can we Sklype and Ichat with that is compatible with both machines? Although a friend has told me it doesn't matter which cam we use because they are USB2, so compatibility is not an issue. Yet, when I did online research looking at one highly regarded Logitech camera, the review said that it is not optimized for the Mac, giving substandard performance. So, I would love to hear from a web cam savant who can handle this issue of web cam compatibility and perhaps offer a suggestion or two about particular cams to explore. Thank you.
