I have a Dell Vostro 1700 and the sound card is not supported, so the microphone does not work and so Skype cannot be used on that machine. Take a look at this thread
I'd love to know about a USB microphone that "just works".
The person that will have to plug it in is a secretary, she won't be able to try around with the drivers.
A mike like this would be good but anyone could do. The important thing is that it just works.
Thanks for any hint
