> Is it as easy as their website says ?

Yes.

> Are there any Skype users here that can tell a little about it ?

I used it for a little while last summer. It works fine, but I am not one for yakking on the phone. This thing encourages talking, and that might eat into your time.

> Do I need a webcamera ?

Pretty sure web cameras are not supported.

> I suppose a headset is needed ?

Absolutely. You'll go nuts trying to use speakers and mike: unacceptable levels of feedback.

> How do you find a persons number ?

Can't remember.

Give it a shot. Headsets are only about $30.
