Free calls within the US and Canada

If you haven't jumped on the Skype bandwagon, now may be the time. Skype just introduced free PC-to-PSTN calls within the US and Canada until the end of the year. Skype is probably already the market leader for VoIP for the masses. This may be one more blow to its competitors, the names of which I can't even remember. I have been using Skype for several years now. It's quality is awesome. The voice quaity is great even when talking to my overseas parents. I just started experimenting with its video capabilities too. It works quite well. Though I don't think the video feature is for me. It may be useful for some, but I don't feel I need to be seen while I am talking on the phone.
