Skype Review

I have used it for some time for free in even US local too. It is fun and reliable and gives clear sound. It is used by thousands of people around th world. I wonder some times how skyp gets benefit of this free service. I also wonder is it trial version? But I love it. I would like to have this service for all the times. I recommend they keep less prices if they make, with the equipmements they do have right now.
