I just got a 1 Month Subscription for $3 just to test it out for the hell of it. Pros -Works on the iPhone 3G. -Can use it with video on your home computer. -$3/month for US and Canada Subscription. Cheaper if you pay by bigger intervals (ie 6 months -You can buy Skype credits if you don't want a subscription. -Free Skype to Skype Calls. -Cheaper and easier to set-up than Vonage. Cons -No emergency number dialing like 911. -Can only use it with Wifi. -Not the best sound quality. -It affects internet bandwidth, to an extent. -Having your own internet phone number is extra. Skype seems like it'd be best for (these are people who use Skype SOLELY, no AT&T): -Stay at home/Work from home people. -Students that are broke as **** but have internet. Best of all, you can just buy a $3 subscription to test drive it for a month. Anyone got more info to add?
