Biggest problem I have with Linux, and it's a show stopper, is no IM client that supports web cams.http://www.skype.com/download/skype/linux/
I do use skype for long distance callsI love it. I can call the US from Korea for two cents a minute. But the people I want to chat with don't usually have access to skype. They generally use internet cafe's and such. BUT.
The point has been rendered academic. Kapote, part of KDE, supports web cams and microphones. A member of a Thailand centric forum pointed me to it in their off topic section. I have set it up and it recognized my web cam just fine. I haven't been able to check the mic yet because none of my contacts are on line at the moment.
The only hoop I had to jump was installing the Jasper Library, which for some reason is not done by default when you install KDE. Which I had to do as I'm using Ubuntu rather than Kubuntu. I found directions for doing that in the Kapote help file. Use the synaptic package manager and search for Jasper. There are only three hits, click to install them all. Wham bam, you're in business.
