Skype is amazing I use it all the time especially to talk to relatives out of the city for as long as I wish and free. I also purchase credit from time to time so I can ring any phone and send sms messages cheap. It works much better than MSN and never cause me any issue, always on no downtime, faster, doesn't hog as much resources but if you're one of those who loves the silly smilies then they aren't as good on Skype. I have my contacts on it and text chat happily as well.

I run it on Linux and Windows no problems, love it and can't get why people use MSN its slow/hungry and always fucking up. Used skype for years now.
